Re: Different results with different environments and proces

Hello,

Updates to the transport module are ongoing. They will soon be available in the new release of the code. We hope they will solve the problems you report.

Cheers,

Re: Different results with different environments and proces

Hello, There are at least two possible reasons to this problem. Firstly, it can stem from a problem with communications in MPI as implemented in COHERENS. Patrick has promised to run additional debugging to investigate this issue. A second possible cause is the way you impose temperature at the boun...
