Solver message 302091

Message text

** ERROR 302091 ** Zero diagonal found in the coefficient matrix.

Explanation

Coefficient matrices are used for the pressure, velocity and temperature solutions. These matrices characterize the influence on a node from all neighboring 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.

Resolution

  • Check the geometry of the model.
  • Contact Technical Support.
