Converting a tooling simulation .sta file format from Abaqus to ANSYS or other conventional formats like STEP can be a bit challenging, as different software packages often use different file formats and data structures. However, there are some steps you can try to take to convert or import the file:

It is also worth noting that even if you are able to convert the file to a different format, there may be some loss of information or accuracy in the mesh or other data. It is important to carefully validate and verify the converted file before using it for any simulations or analyses.

You can import/open it in Altair Hyperworks.
