I used -ksp_type cg -pc_type icc -pc_factor_shift_type positive_definite, but this takes ~300 iterations. > On May 2, 2018, at 12:52 PM, Roy Stogner wrote: > > > On Tue, 1 May 2018, Lee, Jae Ho wrote: > >> Actually, this issue is now resolved. The problem was that the >> default linear solver

Actually, this issue is now resolved. The problem was that the default linear solver was not converging. This issue can be resolved by using a stronger linear solver. Thank you, Mike > On Apr 25, 2018, at 2:56 PM, Lee, Jae Ho wrote: > > I tried the subdivision example provided in libMesh, and

I tried the subdivision example provided in libMesh, and I had some questions about the example that I wasn’t able to find an answer to by myself. In the example (that follows Cirak’s paper from 2000), I see that there are the following steps before the subdivision mesh gets prepared: // Quadri
