Hi Rene Hiemstra,nI'm also trying to run a FSI on my school HPC cluster. Did you figure it out?n I didn't Python to drive system coupling to run. I used this script https://support.nesi.org.nz/hc/en-gb/articles/212642617. But I also faced some problem, such as mapdl cannot connected to system coupling service even though I specified the host name and node name. nLet me know if it helps.Best,nJirongn
