ERROR [2108]: CRITICAL TIME STEP IS ZERO IN EXPLICIT DYNAMIC ANALYSIS

Cause

This error is generated when the time step is defined as 0 due to incorrect data entries in nonlinear explicit dynamic analysis.

Analysis Type

Explicit dynamic analysis (nonlinear explicit transient)

Remedy

This error is generated when the material density is missing or when the elements undergo severely deformation.  First, check the material property data.  Next, check the analysis results obtained thus far.  If excessive deformation of elements is identified, reduce the time scaling factor.  Also, since the severe deformation of elements is related to the element shapes or the magnitude of the loads, check the corresponding data.
