I encounter a problem when I am doing finite element analysis with proe4.0/mechanical

When I am doing finite element analysis with PROE4.0/ Mechaica,

I encounter a problem that I don't know what to do with.

I hope to solve it under your help, it is very important for my study.

The prolem is as follows,

Run Settings
Memory allocation for block solver: 128.0

Parallel Processing Status
Parallel task limit for current run: 2
Parallel task limit for current platform: 64
Number of processors detected automatically: 2
Checking the model before creating elements...
These checks take into account the fact that AutoGEM will
automatically create elements in volumes with material
properties, on surfaces with shell properties, and on curves
with beam section properties.

Generate elements automatically.

The design study terminated abnormally.

An internal engine error has occurred. Please be sure
to run error checking before you run this study. If
you have run error checking, then contact Customer Support.
