When making a copy of simulation, using the same geometry, meshing will ignore MRF rotation zone definition.
Here are steps to reproduce it in my public project:
- Project Fan24Blades > Simulation TriBladeSep > do ‘Duplicate’
- In new Simulation Select Mesh > Create new mesh > Confirm (it will clean the meshing setup)
- Now in that Selected mesh > Copy New Mesh settings from TriBladeSep > select MeshForTriBladeSep
Result: if you Generate new mesh with identical setting (to MeshForTriBladeSep), MRF zone definition will be ignored. I tried it twice and last result is in simulation ‘TriBladeSepInf2’.
I stumbled upon it when trying to add Inflation zone to well defined mesh. I look now for explanation and help from support.
