Hi guys.
I am simulating an industrial fan and after importing mesh from fluent mesher and applying the setting for mrf motion usually after initialization my mrf zone previews only the walls ( blades) and not the whole mesh. The actual problem is that the interfaces become walls and wont let the flow through.
I have set the interface and interface shadow to interior. But in the calculations it acts like a wall !
The other problem is that when i want to change the mrf to sliding mesh the following error occures:
error eval unbound variable
error object change
I have remeshed, changed the geometry, reviewed the setting and.... I have really hit a wall.
The thing is that it used to work just fine !
