ERROR [2105]: CANNOT COMPUTE CONSISTENT TANGENT MODULUS, MATERIAL ID=# ELEMENT ID=# INTEGRATION POINT=#

Cause

This error is generated when the consistent tangent modulus, which satisfies the material data provided in the elasto-plastic model, cannot be obtained.  The error usually occurs when the displacement increment is large or a complex hardening curve zone exists in the material data.

Analysis Type

Nonlinear analysis (nonlinear static, nonlinear explicit transient)

Remedy

1. Increase the number of load increments.

2. If the hardening curve is complex, simplify the curve and perform the analysis.

3. Remove the softening zone of the material model or simplify the curve into a 2nd-order curve of a Bi-Linear form.

4. If the problem persists, convert the model into a perfect plastic material model.
