2 years ago Can you post the output for "single Advection, iterated defect correction Stokes, without gmg" as well?
The only thing I can think of right now is that it has to do with boundary conditions. Are they somehow contributing to the nonlinearity here? I see that we update the constraints only in StokesMatrixFree::setup_dofs(), which is not called between nonlinear steps, obviously.

2 years ago Thanks for the reply. Ah, sorry. I accidentally posted single Advection, iterated defect correction Stokes, with gmg twice, luckely I still have the data from single Advection, iterated defect correction Stokes, without gmg. That case does converge.

The only thing I can think of right now is that it has to do with boundary conditions. Are they somehow contributing to the nonlinearity here? I see that we update the constraints only in StokesMatrixFree::setup_dofs(), which is not called between nonlinear steps, obviously.
hmm, the boundary conditions in this simplified model are all zero velocity, so I don't see how that would be an issue. In the full model I have velocity and traction boundary condition, but I don't think they change with nonlinear iterations, only with advection (which is done online once before the stokes iterations in these schemes).

2 years ago I also looked at the boundaries in paraview and the boundaries do indeed seem to be zero velocity, but the velocities inside are way too large (used the output after 5 nonlinear iterations). That shows I think that it also not just a residual computation problem, but a actual problem with the internal velocities.
Doing a bit more testing on that and just looking at the difference for a full stokes solver with and without gmg gives me significant different velocities, which I find a bit worrying. It is a extremely low resolution problem, but still, the residual in both cases are very small.

The RMS provided by the GMG solver is almost twice the value and the max velocity is more than twice while the residuals are very low. The values in both cases are almost the same for 5 nonlinear iterations, so they are not seem to be converging to each other.

2 years ago I'm not sure it's the same problem, but I just ran the gmg_mesh_def_ghost_nodes.prm test for #4248 and this also shows significant differences in RMS and max vel and iteration counts with and without block GMG. (It uses the normal Picard solver.)

Yes, that looks like the same, although the differences are not as large, but still look significant. What was your residual? In summary there seem to be two issues:

2 years ago @elodie-kendall What would help is having a set of simple(!) examples that currently work or don't work. With that, it would be much easier to find the issue.

2 years ago Hi Menno, we ran a couple of defect correction with GMG tests in the last few days and all of them seem to work okay. I might have fixed recently an issue with incorrect material properties being requested in the GMG solver.
Can you try the problem you have again? Otherwise, any suggestions on how to narrow in on the issue?
MFraters
commented
1 year ago I had tested it and it still didn't work. I have now taken the time to make a simpler example which runs on the current main branch. It still requires the world builder and a bit of resolution, but I took out everything non-standard and got the problem to reproduce on a lower resolution.
With the line set Stokes solver type = block GMG commented out it works and the results look fine. With the line enabled the gmg solver fails (see the last block).
Let me know if you have any ideas on what it could be or what further to test.

Additional information:
Iterative method reported convergence failure in step 1. The residual
in the last step was nan.
This error message can indicate that you have simply not allowed a
sufficiently large number of iterations for your iterative solver to
converge. This often happens when you increase the size of your
problem. In such cases, the last residual will likely still be very
small, and you can make the error go away by increasing the allowed
number of iterations when setting up the SolverControl object that
determines the maximal number of iterations you allow.
The other situation where this error may occur is when your matrix is
not invertible (e.g., your matrix has a null-space), or if you try to
apply the wrong solver to a matrix (e.g., using CG for a matrix that
is not symmetric or not positive definite). In these cases, the
residual in the last iteration is likely going to be large.

Based on @anne-glerum's comment that it might have to do with viscosity contrasts, I explored the issue a bit more. I managed to get the issue to show on a bit under a million DoF's instead of around 63 million. Also, the setup is much simpler (see images below). Again, his is with the current main branch of aspect (using the world builder shipped with aspect) and it works when the line set Stokes solver type = block GMG is commented out.

Additional information:
Iterative method reported convergence failure in step 1. The residual
in the last step was nan.
This error message can indicate that you have simply not allowed a
sufficiently large number of iterations for your iterative solver to
converge. This often happens when you increase the size of your
problem. In such cases, the last residual will likely still be very
small, and you can make the error go away by increasing the allowed
number of iterations when setting up the SolverControl object that
determines the maximal number of iterations you allow.
The other situation where this error may occur is when your matrix is
not invertible (e.g., your matrix has a null-space), or if you try to
apply the wrong solver to a matrix (e.g., using CG for a matrix that
is not symmetric or not positive definite). In these cases, the
residual in the last iteration is likely going to be large.

Aborting!
----------------------------------------------------When I run it I get
Assert `add_angle_inner >= 0 && add_angle_inner <= 1` failed in ../contrib/world_builder/source/utilities.cc at line 894: Internal error: The variable add_angle_inner is smaller than zero or larger then one,which causes the std::acos to return nan. If it is only a little bit larger then one, this is probably caused by that begin and end segment are the same and round off error. The value of add_angle_inner = 1It runs and fails to converge in release mode. I suspect the combination of traction and prescribed flow conditions might be the problem, but I have to play with this some more. Do you think you can change the problem to not use traction boundaries?

1 year ago ah, sorry, I forgot to test the simplfied version in debug mode. I only had to remove the 0 length segments and now it works for me in debug mode (see below).
Thanks for looking into this. I will try to make a case without traction boundaries. I might be able to simplify the slab a bit more as well with less segments so that the file is a bit shorter, I will look into that.

}Don't worry about simplifying the WB file. I am pretty sure there is an issue related to boundary conditions. If the system can not preserve mass due to the boundary conditions, the GMG will fail (while AMG might still work).

static Number dealii::internal::VectorOperations::functions<Number, Number2, dealii::MemorySpace::Host>::dot(const std::shared_ptr<dealii::parallel::internal::TBBPartitioner>&, dealii::internal::VectorOperations::size_type, const dealii::MemorySpace::MemorySpaceData<Number2, dealii::MemorySpace::Host>&, dealii::MemorySpace::MemorySpaceData<Number, dealii::MemorySpace::Host>&) [with Number = double; Number2 = double; dealii::internal::VectorOperations::size_type = long unsigned int]
The violated condition was:
dealii::numbers::is_finite(sum)
Additional information:
In a significant number of places, deal.II checks that some
intermediate value is a finite number (as opposed to plus or minus
infinity, or NaN/Not a Number). In the current function, we
encountered a number that is not finite (its value is (-nan,0) and
therefore violates the current assertion).
This may be due to the fact that some operation in this function
created such a value, or because one of the arguments you passed to
the function already had this value from some previous operation. In
the latter case, this function only triggered the error but may not
actually be responsible for the computation of the number that is not
finite.
There are two common cases where this situation happens. First, your
code (or something in deal.II) divides by zero in a place where this
should not happen. Or, you are trying to solve a linear system with an
unsuitable solver (such as an indefinite or non-symmetric linear
system using a Conjugate Gradient solver); such attempts oftentimes
yield an operation somewhere that tries to divide by zero or take the
square root of a negative value.
In any case, when trying to find the source of the error, recall that
the location where you are getting this error is simply the first
place in the program where there is a check that a number (e.g., an
element of a solution vector) is in fact finite, but that the actual
error that computed the number may have happened far earlier. To find
this location, you may want to add checks for finiteness in places of
your program visited before the place where this error is produced.
One way to check for finiteness is to use the 'AssertIsFinite' macro.

1 year ago hmm, yes, now realized that I did notice that the crash always happened after all the cheap iterations where done and it hadn't converted yet. I don't know the gmg solver well enough to have ideas what could cause this issue. Is the gmg solver using a different kind of expensive preconditioner than the AMG solver? Let me know if there is anything I can do to help looking further into the problem.

1 year ago set Nonlinear solver scheme = single Advection, iterated Stokes
I was reading through the defect correction algorithm but I only now realized that this is just iterated Stokes!

1 year ago ah, yes, I thought that would be a good simplification, since that is what most code was designed and tested for in the first place and most people are familiar with. I should have be more clear about that I used that :)

1 year ago @MFraters, @mibillen I had a temporary fix for this issue (block GMG fails after the cheap stokes in an iterated solver). The fix is to skip the expensive stokes after the cheap stokes. This leads to the solver's failure to reach the linear tolerance in one iteration, but doesn't prevent it from reaching the nonlinear tolerance. The implementation detail in commit 01428009480c6255f45a8c74d71e93e77075bc30
Here is an example's output file: log.txt Timestep 1, failure to converge in iterations 1 and 2, the nonlinear solver still converges to a residual below 1e-3.
not a solution for the issue, research purpose, continue to run with convergence and benefit from the faster speed of the block GMG

1 year ago I just summarize what we discussed 09272023 (@mibillen )
@MFraters mentioned the issue with switching from cheap to expensive stokes, but not if we just use cheap or expensive ones.
@naliboff also observed this issue in their models with large viscosity contrast. But it seems to depend on the rheology configuration.
The GMRES solver restart length and the number of cheap solves are what we could play with. Increasing the first number to 200 or the second number to 5000 seems to work.
Another solution is to take the solution from the cheap solver with a certain amount of solves and skip the expensive interation.
This is my branch with the skip expensive stokes functionality (only one commit). This works fine in my two-d models, the linear stokes solver fails multiple times but the non-linear iterations still converge.

I have run into an issue with the GMG and DC Picard (and by extension the Newton solver). In short,
single Advection, iterated Stokeswith gmg works,single Advection, iterated defect correction Stokeswithout gmg works, butsingle Advection, iterated defect correction Stokesdoesn't work (see output below).I have tried to simplify the problem as much as I could and I have tried to compare the normal stokes gmg solver and assemblers with what happens for the Newton solver, but I couldn't find any obvious reasons why it would go wrong. I also simplified the boundary conditions and the compositional fields. The only way I could get the DC Picard + GMG to converge was if I simplified the temperature structure as well such that there wasn't really a nonlinear problem left.
Here are the aspect .prm file and the world builder .wb file. I haven't been able to reproduce the problem without a world builder temperature field, because with the function parser they either become way to easy or way to hard for the solver. This does require the current main branch of the world builder to be linked to aspect.
@tjhei @zjiaqi2018 any ideas on what could cause this issue?
