Hi, I’m trying to simulate water splash in box baused by gear rotating. I’m new to CFX and I have tried several times, but the results turn out that the water volume fraction is no right., so I will be appreciated for your help.
(1) I read the CFX help document, I noticed that the immersed solid would not interact properly with mutiphase fluid. Since I concerned about the water and airdistribution caused by rotating gear, does the help document means I cannot use immersed solid for my simulation?
(2) I try a gear in a box model and the simulation result seems correct. But I did not define mesh deformation, I’m wondering wether or not the meshdeformation must be defined in situation like mine, I suppose the mesh deformation is required, but how to explain my successful simulatin in the first time.
P.S.
English is not my native language, so I may understand and express mistakely , so please corret me if I made some mistake. Thank you very much!
