Hi @JordiManyer , I think the implementation of the function `numerical_setup!` is missing for `IterativeLinearSolverNS`. When solving a transient problem using an iterative solver, this function is …

The faceNormals in UnstructuredGrid are scaled with the faceAreas which is counter intuitive, because then faceNormal is not a normal anymore but a vector orthogonal to the face scaled with it' area. …

I noticed some numerical instabilities in the BEM coefficients for the WaveBot and frequencies >0.9 Hz. Refining the mesh didn't solve this.

Scipy can optionally use umfpack for sparse solvers. We currently build umfpack as part of cvxopt.
We don't make scipy use umfpack because the wrappers use swig. We need to autogenerate the swig wr…

It might be a fun project to implement a frontal solver to see where we are to develop specialized linear solvers. A starter should be the original paper by Irons [1] which contains a fortran code whi…

When Sage's `MixedIntegerLinearProgram` is used for solving an LP, one frequently needs to access further information about the current basis (often, the optimal basis after solving the LP), not jus…

I was wondering if anyone has tried using the generator on somewhat large problem sizes (i.e. in terms of #variables) and whether the behavior I’m seeing is consistent with what can be expected.
I …
