I'm sorry, I didn't realise I could add screenshots here. That is my model. All the outer walls are set to a constant temperature BC, with the fluid having an inlet and outlet.nAs for using the RGP table, this is my table:nI tried running the simulation with just one material, disabling multiphase and I'm getting similar issues.nAlso, I'm unable to use 2021R1 as I'm doing my Master's Thesis at Bosch, and their HPC only allows 2020R2 in interactive mode.nn
