Hi All,

I am currently doing a simulation with dynamic meshing with a combination of both quad and triangle cells for accuracy.

I have applied the UDF for both my object and the surrounding quad mesh so as to allow both of them to move within the triangular mesh as one whole rigid body.

However, as time passes, the quad-mesh becomes more and more skewed till the point that I receive "negative cells".

From what I observe, the quad-mesh seems to move slower than my airfoil even though the same UDF was applied to both of them.

May I know what am I doing wrong?
