Card "FREQUENCY" is not allowed for this subcase type.

Hi to everyone

I am running a non linear quasi static analysis on hypermesh 2017 (optistruct) with contact surfaces

When I run the analysis I get the following error:

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

Can someone help me?

Actually, you don't need to assign 'FREQUENCY' in the loadstep definition for a quasi static analysis . That field is for frequency response analysis.

Sorry for not explaining myself very well, but the problem is that I haven't assigned any 'FREQUENCY' card, it appears on its own as an error, ergo I didn't put any frequency in the input data but the error says otherwise.

Could you please share the .out file of the run for quick look?

Ok, thank you, I solved from the .fem file deleting the string which contained the frequency card.
