CFD/DEM part of coupled simulation fails for no apparent reason

Created by Alice König, Modified on Thu, 11 Jul, 2024 at 3:21 PM by Alice König

Aspherix and the CFD solver are executed as separate programs and, therefore, each side has its own output stream. Both are usually redirected into separate files – this is, for example, the default behavior of cfdemSimulate. If the CFD fails, for instance, this might be due to a failure on the DEM side (e.g. due to a wrong command) and vice-versa.


This means that you should check both simulation outputs to find the error’s root cause.
