Solid body 2-axis Rotation Problem

hongsuny2333 · December 28, 2015, 22:30

I want the Z-axis Torque[N.m] calculation by CFX.

The Solid body is in fluid.
The Solid body is continuously rotated in the Z-axis and rotated by 90 degree repeatedly in the X-axis.

Is there any way?

Please. Help me.

There is a CEL expression to do this if it is a wall face: torque_z()@rotor surface

If it is a rigid body you can get it from the rigid body variables. See the reference manual for available variables.

Thanks. ghorrocks
My problem is how to express the motion of a solid body.
Is it possble Immersed solid?
or remeshing method?
or other easy way?

I wonder. Method for rotating the z, x direction in the one object.
I try MFR, Immersed solid but I'm fail.

You may need to post some images of your current progress.
If i am not wrong, it could be done using any of the techniques or combination of techniques that you have mentioned.
