John, I did and it worked perfectly the problem is I can't mesh my original problem in libMesh. Ata On Jun 12, 2013, at 5:44 PM, John Peterson wrote: > > On Wed, Jun 12, 2013 at 4:34 PM, Ataollah Mesgarnejad > wrote: > Cody, > > You were right that seems to be the problem. CUBIT splits th

Cody, You were right that seems to be the problem. CUBIT splits the HEX cells differently on the two different surfaces thus the error. Now is there a more general way built in libMesh to enforce periodic BCs without requiring nodes to be exactly translated? Thanks, Ata On Jun 12, 2013, at

Dear all, I have prepared a small example code that tries to assign periodic BCs first to a HEX8 mesh and then to a TET4 mesh (which crashes in debug) you can get it here: https://dl.dropboxusercontent.com/u/19391830/sample_periodic_bcs.zip David, Thank you for your response. I don't really g

Do the nodes on the periodic boundaries match up with the tet4 mesh? If not, that will cause an error. I recall a thread where this issue was discussed. On 06/12/2013 03:27 PM, Ataollah Mesgarnejad wrote: > Dear all, > > I'm trying to set periodic BCs on a very simple 1x1x1 cube. When the cub

Dear all, I'm trying to set periodic BCs on a very simple 1x1x1 cube. When the cube is meshed with HEX8 everything goes smoothly but as soon as I switch to TET4 elements I get a series of errors like: 0] ../../src/fe/fe_map.C, line 1188, compiled Jun 12 2013 at 13:28:03 WARNING: inverse_map of
