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

    Hi tob.hohmann

    The solver is indicating that the second field MTXNAME - Matrix name defined on ASSIGN,H3DDMIG. is blank and not defined coorectly in your DMIGMOD card,

    Please redefine this card , see - Altair OptiStruct > Reference Guide > Input Data > Bulk Data Section:
    DMIGMOD

    Hi, I'm having the same error. What should I put in the MTXNAME field of the DMIGMOD card? What does it mean? 

    Thanks in advance!
