Creating Zones from the stl file
 

Dear All,

Could you please tell me how to define a couple of zones under one geometry from the stl file??

I am aware of using cellSet and faceSet which will be used to create zone, however, under cellSetDict or topoSetSources I don't know what to put into there? i.e. boxToCell, surfaceToCell, etc.

Thank you very much for your time!

Have a nice day (or night)!!

John
