Hi i am trying to run a simulation for a pipeline with natural gas that is injected with H2 (vertical pipe).
The simulation runs fine when i am not using udf (so the mesh and setup, initialization etc are okay i guess). As soon as i try to load udfs problems occur. I have one c file that has the 4 equations i need. The first problem occurs when i press build: Error: The UDF library you are trying to load (C:\Users\evipa\Desktop\8\Sim_files\dp0\FFF\Fluent \libudf) is not compiled for 3d on the current platform (win64).\n\nThe system cannot find the file specified. \n\nC:\Users\evipa\Desktop\8\Sim_files\dp0\FFF\Flu ent\C:\Users\evipa\Desktop\8\Sim_files\dp0\FFF\Flu ent\libudf\win64\3d\libudf.dll Error Object: #f (I make sure to delete the previous udf in the library before building again) Despite the message, when i go to manage it shows the udf, so i can load it. Then i put the udf in the materials i use (at the fluid and mixture folder), and do initialization again (haven't changed anything else from the original simutalion that run without udf). Then i keep seeing the same 2 errors over and over again: reversed flow in 5 faces on pressure-outlet 9. # Divergence detected in AMG solver: species-0 -> Increasing relaxation sweeps! # You may try the enhanced divergence recovery with (rpsetvar 'amg/protective-enhanced? #t) -------------------------------------------------------------------------------------- Error: Divergence detected in AMG solver: species-0 Error: Divergence detected in AMG solver: species-0 Error Object: #f Any idea on what to do? I keep thinking that the problem is because of the compile but idk how to fix it. Thanks in advance. Yours truly, A desperate student |
