Remote Displacement with polar coordinates
I had a problem, described here about moving the centroids of 12 plates placed cirularly along a tube in polar direction. I got a very helpful answer from SandeepMedikonda to use remote displacements to catch the centroids of my rectangular surface. That worked well so far, the only thing, I was wondering about, if there is a possibilty to use polar coordinate systems to indicate the direction of the remote displacement. I had defined a polar coordinate system and wanted to selct it for the remote- displacement - but I couldn't. It just lets me select cartesic coordinate systems. So I calculated by hand the (cartesic) x and z- component of my displacement with basic trigonometric functions. This worked of course, but I was wondering, if there is no possibility to specifiy a displacement in polar coordinates.
Had anyone faced a similar problem and knows how to solve it?
