ERROR [2004]: FAILED TO COMPUTE EIGENVALUES

Cause

This error is generated when eigenvalue calculations are abnormally terminated due to numerical problems.  By and large, problems exist in the analysis model, and additional error messages may be generated.

Analysis Type

Mode-based analysis (modal, linear buckling, modal response)

Related Menu

None

Remedy

Since most problems are associated with the analysis model, check to see if the model has been properly constructed.

The main variables in eigenvalue analysis are mass and stiffness; thus, check if the mass density has been correctly entered in material properties or if the unit system for the density has been properly defined.  Also, in case additional mass has been added using a mass element, check to see if it has been defined with the mass unit.
