Possible bug in creating fem file with long loadstep ID

Dear Community,

 

I would like to present you a possible bug I found in Hypermesh 2017 when it creates the input file for optistruct including a buckling analysis (due to limited time, I have not checked if the same problem appears with other analyses).

 

Please find attached an example and refer to the example for the description below.

 

When you try to create the Optistruct file to run (for analysis only, -optskip), Hypermesh creates the following subcase card for buckling:

 SUBCASE12345678   LABEL Linear Buckling ANALYSIS BUCK   SPC =        1   METHOD(STRUCTURE) =        3   STATSUB(BUCKLING) =       1

The first row is missing a space and the solver gives you the following error if the space is not added manually:

 *** ERROR # 1461 *** in the input data:  Card 'LOAD' is not allowed for this subcase type.

The problem seems to be present only if the loadstep ID is made by 8 digits.

 

I hope this will be helpful to somebody.

 

 

Regards,

Alessandro
