Hello everyone. Days ago I had mesh problems for both surface mesh and volume mesh like this picture shows:


Soon I realized this problem is from faulty geometry:


Sorry about these pictures, I’m not sure if you can see these lumps..

The original cad model has no problem at all, it is created in solidworks. But after I input into ccm problem starts, and CAD repair function inside ccm dosent pick the problem up.

I have tired inputting same model with different types of file. It actual made different! Also the “Tessellation Density “ option makes difference as well.
But no matter what I try, there is always some lumps by edges! What type of file do you guys use to input into ccm?

Thanks
