How to add both rotation and Translation simultaneously for a geometry.

Please login with a confirmed email address before reporting spam

Hello,

Recently, I creat a geometry with helix shape. I need helix rotate with its central axis, so the rotation movement will be transformed into translation(forward) due to helical shape. Now with the Moving Mesh Interfaces, I can only realize the helix rotate with its central axis,but it not translation, only stay the original place and rotation.

In addition, I also try the prescribed deformation, with dx = cos(2pit1[Hz]) dy = sin(2pit1[Hz]) dz = t*1[m/s] But, this a whole tranlation without rotation with its central axis.

So, could u please give me some suggestions about how to apply both rotation and translation for a helix shape, and with its rotation with its axis, it can realize translate forward.

Thank you for your help and looking forward to your reply.

Best regards Hou

Hou,

I think the expressions for the prescribed deformation are not complete. Shouldn't the x and y movement comprise the radius (e.g. sqrt(x^2 + y^2) and the z movement should comprise the pitch of the helix?

Cheers Edgar
