Ansys EmployeeHello,
Error "termination due to out-of-range-forces' indicates that there is instability in the simulation.
Here are some general tips for how to combat instabilities:

https://www.dynasupport.com/howtos/element/negative-volumes-in-brick-elementsGood practice is to locate where are the nodes/elements that give this error, it should be indicated in the message file (mess00XX MPP or messag -SMP), and visually inspect a model.
Please let me know how it goes,
Thank you,
Alex
