Let's start this with the following test problem: we have u'' = 0 with boundary conditions u(0) = 0 and u'(1) = 1, i.e. a truss with left boundary fixed and force F=1 is affecting to the right end. Us…

Looks that we might have a problem with either stiffness or mass matrix. Here is the test code which can be used to validate the results:
```julia
using JuliaFEM
using JuliaFEM.Preprocess
using …

Just ran into pyamg; great to see these complex algorithms be made available in such a neat package!
I started to try out pyamg in some of the more complex solves in my project, and these gave the …

Dear Li-Yi Wei,
I'm working with your code for my thesis and am working on getting rid of some of the 'for' loops in your topopt class. To be more specific those used to generate the global stiffness…

Dear Alex!
I tried to use pyansys to get stiffness matrix from a fullfile. When I ran the code with my fullfile, it showed the following error message: negative dimensions are not allowed
The code…

This issue is to include the hinges/supports (see [PR](https://github.com/KratosMultiphysics/Kratos/pull/1452)) in the interface
What is needed from the GiD side is a selection window (similar to l…

In shape optimization, we calculate the primal solution several times, between the solution steps, we are modifying the shape of the structure.
The problem is, that the solution from the previous sol…
