Error in FEM Analysis

Rahul_P1

Hello,

In our study work we ought to optimize a motorcycle frame.

In Hypermesh we generated settings which are displayed in picture 1.

During the solverrun the following message appears:

*** ERROR # 1000 *** in the input data:
Incorrect data in field # 2.
Expected STRING, found BLANK.

Can you help me?

Thanks
