** ERROR 220038 ** Zero diagonal found in the coefficient matrix.
Coefficient matrices are used for the pressure, velocity and temperature solutions. These matrices characterize the influence on a node from all neighbouring nodes. The diagonal term represents the influence of a node on itself. A zero diagonal means that a node has no influence on itself which is physically unrealistic. This error means an unexpected problem has occurred in one of these finite element matrices. The most common cause of this error is that no curing time has been specified for a 3D thermoset analysis.
If the process type is 3D thermosets, check that a non-zero curing time has been specified in the process settings. Otherwise contact Technical Support.
