Re: [petsc-users] Convergence of AMG

Var: 0,…,5 are the 6 variables that I am solving for: u, v, w, theta_x, theta_y, theta_z. The norms identified in my email are the L2 norms of all dofs corresponding to each variable in the solution vector. So, var: 0: u: norm is the L2 norm of the dofs for u only, and so on. I expect u, v,

Hi Dave, Indeed, I added that last arg myself after the configure script asked for it (--with-batch seems to need it). I just tried with petsc-3.9.1, without the --with-batch and --known-64-blas-indices=1 options and everything is working nicely. I will try again later with the latest version. Th

Hi, I am attempting to solve a Mindlin plate bending problem with AMG solver in petsc. This test case is with a mesh of 300x300 elements and 543,606 dofs. The discretization includes 6 variables (u, v, w, tx, ty, tz), but only three are relevant for plate bending (w, tx, ty). I am

Matt, How difficult would it be to impose such boundary conditions with DMPlex? Presumably you just connect the mesh up "properly" and it is straightforward? Barry > On Oct 27, 2018, at 10:23 AM, Matthew Knepley wrote: > > On Sat, Oct 27, 2018 at 2:02 AM Fengwen Wang wrote:

Hi petsc-users, I am experiencing problems running ex5 and ex7 from the slepc tutorial. This is after upgrade to petsc-3.10.2 and slepc-3.10.1. Has anyone run into this problem? see the error message below. Any help or advice would be highly appreciated. Thanks in advance! Santiago trianas@hpc
