Hi to everyone I have to simulate a gear pump for finish my study, do you know what is the best way? I had try to make a simulation with mesh deformation but i have a lot of problem i don't know a lot of things,how can i make the step next the first?.... In the tutorial 20 i see the way that i have to follow but there is a lot of things that i don't know what i have to do for my pump. the tutorial 20 run good but when i try to follow that way for my gear pump there's a lot of trouble. When the solver try to update the mesh give me a error an create about 200000 negative volume and crash the solve...Help me please or tell me where i can find a help.. Thanks so much have a nice day Elia Zenato
