Hi All, I am working on the implementation of 3D electromagnetic forward solver for geophysical applications. I am following the algorithm as described in Grayver and Kolev, 2015. The system is solved with preconditioned FGMRES method. However construction of the preconditioner is not straightforward, and so far I used direct solver for this. Unfortunately direct solver requires a lot of memory for medium size 3D problem, and this is why I want (as suggested in Grayver&Kolev) to use CG with auxiliary space preconditioner AMS instead. The implementation of AMS is readily available in Hypre library which should be possible to access through PetSc. I struggle to understand how to do this within deal.ii. Is there a PETSc wrapper for this.
Any help will be greatly appreciated.
