Error 402 FRF analysis


Updated by Altair Forum User
Hi,
I have to set up a FRF analysis. As Load I have to use acceleration vs freq. Inside of the Card RLOAD1 i have define EXCITED (using SPCD) and TC (using TABLED1). The solver gives me this error. What can I do to solve it?

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.

Hi,
Can you provide F1 say as 1 instead of 0 adn check if that helps?

In F1 could you set frequency as fundamental frequency or 1
Please make sure to set type as acceleration in Rload1 card. If possible share .out or .fem file to take a quick look.
