ERROR [2104]: SINGULARITY WHILE COMPUTING CONSTITUTIVE MATRIX IN ELEMENT ID=#

Cause

This error is generated when the performance of an element becomes very poor due to severe distortion during the analysis.  The error generally occurs in a model at a level similar to the NEGATIVE JACOBIAN error.  Also, this error is generated only when hybrid elements are used.

Analysis Type

All types of analyses except for explicit dynamic analysis

Remedy

1. For linear analysis, search for the elements identified with the error and modify the shapes.

2. In case of nonlinear analysis, such an error occurs when significant changes in loads are present.  Increase the number of load increments.  Refer to the remedies for ERROR [2103].
