[Libmesh-users] libpetsc.so: undefined reference to `nc_def_var_deflate'

Dear developers, (I appologize if you are getting multiple copies of this, I sent this email previously using my other email address that I don’t think is in the list.) I’m getting a NetCDF symbol error when I try to compile libMesh (commit a58bb96d07c20eb541b557b0053269e6d8c92f15) vs PETSc 3.7

[Libmesh-users] pre-partitioning a big mesh

Hi all, I am working with a relatively large 3D exodusII meshes 15-50 M elements that I create using Trelis (CUBIT). Right now I have crude procedure to pre-partition this mesh on a machine with a large memory basically by reading it in a small libMesh program and then writing it out as a nemes

[Libmesh-users] project_solution from a ParsedFunction to a system with more than one variable

Dear all, I’m using project_solution from a ParsedFunction to set the initial values on an ImplicitSystem. This works wonderfully if the system has only a single variable but not surprisingly (sinc

Re: [Libmesh-users] pre-partitioning a big mesh

Hey Roy, It took me a while to pull/recompile on both machines. Unfortunately the mesh.read still crashes with: Reading mesh /data/mesgarnejad/Crunch/Li-ion/NotchedSphere/mesh/55c1b7e69754d48aef2c03b2f6ead63309b4e3ba.cpr… Assertion `pid == old_node->processor_id()' failed. pid = 2 old_node

[Libmesh-users] new libmeshdm fails with newtonrsls

Hi, The new implementation of the libMeshDM unfortunately fails when using variational inequality solvers VINEWTONRSLS or VINEWTONSSLS (for example miscellaneous/ex7). This happens when PETSc tries to VecDuplicate the solution vector for lower bound in src/snes/impls/vi/vi.c: 383 ?! I pulled

[Libmesh-users] Hisotry variables

Hi, I’ve recently added plasticity with implicit integration to my code. This requires keeping track of so called “history variables” (i.e. internal parameters of plasticity such as back stresses, equivalent plastic strain,..) on each quadrature point. I have come up with a crude work around th

[Libmesh-users] Clough-Tocher finite elements FECLOUGH

Hi, I was wondering what is the local numbering of the DOFs for Clough-Tocher FE on Tri6 elements? I’m looking for a way in each element to loop over the basis value (not the gradient) DOFs. Thanks, Ata ___ Libmesh-users mailing list Libmesh-users@l

[Libmesh-users] FEClough periodic BC

Hi, I noticed that periodic BC does not work for FEClough. I see the functions for it but I’m guessing it was never implemented. My question is wether periodic BCs do work for FEHermite or is there a reason why the current implementation would not work for C1 basses. Thanks as always, Ata ___

[Libmesh-users] new PetscDM implementation does not work with Dirichlet BCs

Hi, I pulled and built libMesh after a long time (~2 years) recently and noticed that the new implementation of PetscDM does not work with DirichletBoundary class anymore. Anytime I try to set the dirichlet BCs for the problem when running with petscdm (i.e. using SNES types vinewtonrsls or vin
