Hello everyone,
I am trying to model a simple Shell and Tube heat exchanger.
I have always the same meshing problem. Sometimes if meshing succeeds then during computing the message of avoiding inverted elements pops up.
-Pictures of problems, the geometry, etc. are added !
-I tried to add boundary layers, but comsol fails to create some boundary layers always for the same domain.
I changed the number of layers and I select the walls of the tubes, but always inverted elements stay.
-Other error that had popped up once: Domain element has wrong number of neighbours
-The domain that fails is the fluid over the tubes. This domain has two numbers: 3 & 4 like showed in added pictures. Is this some problem that this domain is twice defined by itself?
Thanks a lot !!
Hopefully someone will be able to solve this :)
