Solver message 221081

Message text

** ERROR 221081 ** PVT: negative density encountered.

Explanation

The density is obtained from the pvT material data model. If the model coefficients have been fitted correctly, then calculated density values will be reliable in the range of normal processing conditions. If a negative density is returned from the pvT functions, it indicates that either the flow solution has become unstable, or that the pvT material data coefficients are incorrect.

Resolution

• Check the pvT coefficients for the current material.
• Check the viscosity data for the current material.
• Select a different material.
• Allow a small transition time for large pressure changes between steps in the filling or packing profile.
• Check the model for defects.
