This command is used to transform a mesh. The transformation is expressed as diplacements in cylindrical coordinates $(R,\theta,z)$.
$R$ is the radius, $z$ is the axial coordinate and $\theta$ is a circumferential angle ranging from $0^\circ$ to $360^\circ$.
If fid${}_1 \neq$ fid${}_2$ inner and outer surfaces use different radial transformations (see example below).
In such situations only nodes on the surface of the body are transformed. Interior nodes are not treated.
However, all nodes are transformed in the radial direction if fid${}_1 =$ fid${}_2$.
Interior and exterior surfaces
Example
Transform mesh cylindrical - inner surface
Example where only the inner surface is transformed.
Same radial transformation of inner and outer surface Transform mesh cylindrical - spring
Example using transformation displacements in axial and circumferential directions. A short cylinder is transformed into
an object with the shape of a spring.
*PARAMETER
Ne = 200 # number of elements
D0 = 1.0e-3 # spring thread diameter
D1 = 1.0e-2 # spring coil diameter
Ls = 4.0e-2 # spring length
Nr = 8.0 # number of revolutions
Ps = (%Ls-%D0)/%Nr # spring pitch
eps = 1.0e-5 # initial cylinder length
sf = 2*pi*%Nr/%eps # transformation scale factor
