How to create the twisted helical shape in the COMSOL using parametric equations??

I know that it is a very easy task. but somehow, I am unable to obtain the twisted structure. I desired helical model, governing equations for helix and my mph model are attached below.

Please help me.

I have finally found the solution. my equations and procedures are correct. I just required to change some parameters in the sweeping process.

Motion of cross section == Twisting == Follow curvature vector

advance setting == geometry representation == Bezier (optional)

Hope it would be helpful for someone.
