Now I get this error message as I run Acusolve, any tip?
Time step 0.1 sec might be a good starting point.
Please upload .inp and .Log file. If necessary, rename the extension to .txt.
Here it is.
The problem was the Time was supposed to be Piecewise Linear.
With that one change it runs. Input file attached.
BTW, you would need to makes considerable changes to get useful results. Mesh is too coarse to get any accurate results. Also Nodal Output would be have to be changed to lesser value (e.g. 1 or 10), instead of current default 1000.
If you have not attended any training, I would recommend to visit an AcuSolve training at the nearest Altair location.

Thanks, the Time should be change only in the multiplier function or where else did you put Piecewise Linear
Please compare the .INP file I uploaded with the one you uploaded /emoticons/default_wink.png' alt=';)' srcset='/emoticons/wink@2x.png 2x' width='20' height='20'>
