Error in CFX Solver for mesh motion
 
1 Attachment(s)
Hi,

I am trying to model flapping motion of airfoil. My questions are

1. After some iterations there is negative volume error being generated so what should I do to avoid that.


2. I tried the remesh option available in cfx solver, but it rotational displacement about centroid or any other point is neglected in remeshing. See image [its from cfx manual], so any solutions?

Any help will be appreciated.

I suspect you may need to contact CFX support for help with this.

Don't use ICEM CFD Replay method for remeshing. This is only good if you have the conditions you have outlined.

Use the User Defined remeshing associated with an ICEM remeshing script.
