Hello
I am working with a 2D microeolic system. I am setting 6DOF simulation configuration.

After a lot of work i arrived at this point:

• I set the smoothing and remeshing options properly;

• I hooked the DEFINE_6DOF_PROPERTIES with mass and inertial moments properly to the rigid body;

The problem is that, when i start the mesh motion, the wings start to move horizontally, instead of rotate, creating a negative volume.

I know that the problem is related to the CG properties, so i wrote the DEFINE CG MOTION UDF but i cannot hook two UDFs together for the same body.

What should i do to set these properties together?
There are other methods to solve the problem?

Thank you for your attention
