The solver fails and prints the following message to the output file:
****** FATAL ERROR ******
The orthographic view transformation failed on domain interface "GGI".
Failure may be due to r=0 included in transformed cylindrical coordinates of an interface
with rotational relative motion.
Make sure that the axis of rotation is specified correctly.
As the message indicates, the solver cannot solve on a frame change interface where the radius goes to zero.
A more common reason for this error, however, occurs because of the orientation of interfaces.
The solver performs an intersection on each domain interface based on either constant r (radius), or constant Z (or axial direction), not both.
Errors can therefore occur when one domain interface is made up of surfaces that have both constant r and constant Z.
The solution is to create separate domain interfaces such that the surfaces that make up each interface lie in either constant r or constant Z.
