Solver message 305531

Message Text

** ERROR 305531 ** One or more requested density derivatives were not set in the user API function "XXXX" when it was called by the solver. Refer to the Solver API Reference documentation for this function.

Explanation

An incorrect value for one or more of the specific volume derivatives was returned by the user function named in the message. The 3D Flow solver requires values for the material derivatives : thermal expansivity, compressibility and (for thermoset materials) the cure expansivity.

Resolution

Review the detailed information about the function in the Solver API Reference documentation, available in Synergy. Ensure that your user function returns appropriate values for the derivatives.
