KNOWN ISSUE: Kinetic theory model in multidomain cases (Class 3 Error if it were not mentioned in errata)
When using the kinetic theory model for multiphase granular flows with multidomain problems, the CFX-Solver may stop with a segmentation violation because of a bug discretizing the dilatational stresses at GGI interfaces. In addition, the dilatational stress contribution to the viscous work model of the total energy equation is incorrect.
This is caused by errors in the coding of interfaces for the kinetic theory model.
No workaround is currently available.
