Custom Linear Solver

Please login with a confirmed email address before reporting spam

Hi,
I'm wondering whether it is possible to use custom linear solver for my model on comsol.
For example, can I use my original solver implementation instead of MUMPS or PARDISO at Study ->Solver configuration -> Solution -> Direct Solver -> Solver?

Seki-

I would recommend looking into using the "Assemble" feature. Right-click on the Solution node which is found within the Study node. Then, select Other>Assemble.

Select the appropriate check boxes for the matrices and vectors you want to inspect or modify and save the model as a model file for Java or export to tabular format. You can then have the raw system matrix data available if you'd like to use your own solver.
