Modal Masses are not shown in .outfile when running analysis via .fem deck file

Hello Everybody,

I recently wanted to automate my analysis a little bit. Since I have to run the same analysis again and again for different models I created a solver deck (.fem) file that contains all the analysis parameter, so I don't have to define them in the GUI for each model. The varying models are added to this deck with the 'include' command.

Everything is working fine so far and I get the same results as for the original model.

However, when I perform a modal analysis I do not get the modal effective masses or participation factor output that I usualy get in the .out file altough I used PARAM,EFFMAS,YES in my modal solver deck.

When I import the solver deck in the GUI and add the PARAM Control Card manually, I get the desired values.

So, is there a reason I don't get it when defining it in the solver deck only?

 

Any advice is greatly appreciated.

Thanks in advance and best regards

Leon

    PARAM card need to be added inside the BULK DATA section.

     

    This means that it need to be after BEGIN BULK and before ENDDATA

     

    So, it should be:

     

    ...

    Subcases

    ...

    BEGIN BULK

     

    PARAM,......

    NODES..

    ELEMENTS...

    MAT...

     

    ENDDATA
