Hello,

in my model I have actiavted FSTOSZ control card to automatically generate a size model after my free-size optimization. But during the optimization no *_sizing.fem files are created.

Any suggestions?

Is there any possibility to create my size-model without the Sizing.fem files?

Thank you!

    Hello,
    One reason can be your FSTOSZ parameter is not correctly set.
    What do you have in your fem file ?
    Can you try with :
    OUTPUT,FSTOSZ,YES,SPLITALL

    One other possible reason would be in case you launch your optimization on server, and the script you use does not recover fem files (meaning the fem while is created but not provided to you at the end of the calculation)
    Do you launch the optimziation locally or on a server ?

    If we identfity that it is one of those reason, you can modify either the FSTOSZ parameter or your server script, and re-launch only the last iteration of your optimization. This way you get your result in minimum time.
    This is done with the RESTART feature.
