Thanks for your input. I had a look at the referred documentation. However, it states that the external data is static and therefore only read in the analysis set-up. I was able to do this with the *TREAD command as well, but my problem is that it doesn't re-read the file at each coupling (time) step. Do you have any suggestions to solve this problem? Which command(s) should I use to issue the *TREAD command (updating the pressure table) at every coupling step? For Ansys APDL, it works well to use the *TREAD command at each load step, but Ansys APDL sees the system coupling process as a single load step.
