Simcenter STAR-CCM+ Mass flow reports involving some derived parts return different values depending on core count

Simcenter STAR-CCM+


A report has been received of a case where the mass flow report on 8 cores was different from the report using 256 cores.

Defect Last Update Date: 2021-Mar-09
Version Discovered In : STAR-CCM+ 2020.3
Version Fixed In : STAR-CCM+ To Be Confirmed

In affected versions of the software, the value of a mass flow report computed when the simulation ran on 8 cores differed considerably from the value obtained when running on 256 cores. The mass flow report contained thresholds of plane sections indicating that the issue might be restricted to certain kinds of derived parts. The problem has now been resolved in development versions of Simcenter STAR-CCM+.
