Hello everyone,
I would like to simulate a SOFC with the help of Ansys Fluent 2023 (SOFC with unresolved electrolyte). My model and description of all components are attached. I have a wall to wall-shadow relationship between anode and cathode, which means that I do not resolve my electrolyte. The electrolyte is only defined by a thickness in the SOFC calculation console.
I set all the boundary conditions and initialize the problem. Up to this point, no errors occur. As soon as I want to start a calculation, I get the following error code:
999999: mpt_accept: error : accept failed: No such file or Directory

After receiving this error, Fluent crashes immediately. In several online forums I could already find the information that Fluent should be started in series instead of parallel. This is not possible in Ansys Fluent 2023 (unlike in 2019!). Depending on how many cores I use, I get the same .txt error code file x times. I have a suspicion that there is incorrect access to the cores, to which I could not find an answer.
