Dear petsc developer,
We are considering use complex matrix for eigen value decomposition via
slepc will keep DC/Tran simulation in real world.
We can, compiler each solver (AC, DC, Tran, etc) as dynamic library
(.so), and load them by dlopen.
So, is it possible, each time we load a solver, which links to
real/comples petsc, to do the simulation. After that, we dlclose it and
load next solver.
And another question is, we must keep MPI commnucator in the main code
and call PetscInitialize/PetscFinalize in the so, it seems petsc support
this mechanism, right?
