Can I get an update on the latest protocol recommendations (at least in the saltswap context) in terms of number of perturbation vs propagation kernels? As I understand it the issue is that perturbati…

I have a non-linear program
```Julia
juniper_opt = optimizer_with_attributes(Juniper.Optimizer, "nl_solver" => Ipopt.Optimizer, "mip_solver" => Gurobi.Optimizer)
model = Model(juniper_opt)

Dear Sir,
Attached you may find the data file (data_135.txt) and the PyReSpect output (disc modes) for that data (dmodes.txt). The input data is a stress relaxation test conveyed in a given tempera…

Dear developers,
Thank you very much for developing such a powerful tool to calculate various physical quantities.
I am currently trying to learn nonlinear optical properties like shift current and …

Allow initialization of Walberla LB with:
* Viscosity and magic number (defaults to 3/16). For eqn see LB specializations
* Or with the full choice of four relaxation rates omega_shear, bulk, odd even…

### Describe the bug
When using ABACUS to do structure relaxation calculation, I find that the amount of the memory used will gradually increase with the calculation steps. I use the `top` command t…

The initial value and gradient is undefined because the start value is `y = 0` and there is `1 / y^2`
This could be classified as expected behavior?
Ipopt is able to solve the model.

### Describe the bug
I used ABACUS to do the relaxation without vdw and got a structure. After this, I used the relaxed structure to do the relax with vdw, but there was no change to the structure.
