I want to do a simulation of two separated degrees of rotating freedoms for a sphere domain.
But in CFX-pre it limits that only one rotating axis can be defined in one domain. Please help me, thanks a lot! |

if I properly understood you ,first set up additional coordinate system.
Defining a second doainm, select the second coordinate system |

In CFX-pre, You can add as you want new Coordinate frames (tree on left site-coordinate frames- right click-inser-coorddinate frame, named -and decide how and when the new coordinate system will be.)
Then, when You create a new rotating domain, in the Location and type- coordinate frame , choose You newly created, and on the bottom, in AXIS Definition, choose axis ( Global XYZ for COORD 0; 1.1 1.2 1.3 for Coord 1 etc) |
