zcj19910605 is on a distinguished road
Hi all,
I am a undergradute student trying to simulate the unsteady flow in Francis turbine. i'm trying to use the dynamic mesh, but it comes out the guide vanes rotates as wish, but the meshes near the GV walls are not spilt or merge automaticlly, thus the fluent code always shows the negative cell volume error.
Can anyone help me with the 3D dynamic mesh problem?
Thank you in advance.
