We can not see anything in the message above, did you want to post something ?
If you still require help:
Run the model with one elastic body (not rigid) fixed support and a force and runwith LS-dyna in 2021 R2.
Show the screenshots of your set up in an image (the image should include the Ansys logo with version and release of ansys on the top right in the model window, so we can see what release you are using, because you did not answer that before - please do answer these questions otherwise we will not be able to help).
Finally and most importantly and for us to find why this happens and to resolve, go to solution information and copy paste the whole text there (this can also be found in the solver file directory and the file is called message), and put them inline in your post so we can read that text (do not add it as attachment please).
