Hi @Tachs77
Can you share an image of FREQ1 card you have in your model?
Looks like the number of increments you have is zero on the card.
I'm sure I have set up the RLOAD1 type as acceleration.
In the image there is my FREQ1 card and the increase is not zero. I realized that if I change the starting frequency from 0 to 0.25 the analysis starts. However, it is not the kind of analysis I want to perform. I uploaded .out. Thank you very much.
Please make sure to set type as acceleration in Rload1 card. If possible share .out or .fem file to take a quick look.
