I've run into an insurmountable problem when I tried to run a flow simulation.
The situation is simple - air at 293 K goes into one channel, air at 400 K goes into another channel, and some helical elements mix the two air flows together, as shown in the following image:
However, whenever I would try to run the simulation, I would get an error message saying (I quote):
Fluid Subdomain 1 - Rebuild Errors: Faces of this feature belong to different regions.
Not sure exactly what went wrong - I've gone to instructional videos on Youtube and followed the instructions down to the letter, and I'm still getting this error.
Will appreciate any help here. Thanks.
What is the link to the tutorial you followed?
The error is because 2 sub domains can't share the same space.
If both inlets use air, there is no need for a fluid sub domain.
