hi all.
I'm using a hexahedral volume, dT = 0.000016667s, each time step 0.1 deg rotation All faces adjacent to the rotation domain are interfaces. I'm trying to analyze a coaxial inverting propeller, but I'm having a bit of a problem. The domain proceeds as front blade volume > stationary volume > rear blade volume, and the front and rear rotate at the same speed and in different directions. Problem 1. There seems to be a mesh regeneration error when two forward and backward rotation domains rotate over time, so a negative volume is created and the calculation does not proceed what i did 1. Check the geometry 2. Check the volume 3. Check boundary conditions ( Cell > MeshMotion , Interface Periodic Rotation , Rotate on Walls Created by the Interface ) 4. Dynamic mesh What else can I do? Oh, by the way, the side of the front blade and the rear blade is the square Mesh |
