Default Cylindrical coordinates
Posts: n/a
Hi everyone

I am trying to run a CFX stirred tank sliding mesh simulation. My geometry is in x, y, z coordinates but when I run the file I use a fortran file USRGRD which converts the cartesian coordinates into the cylindrical files. This however gives me force on solids in only x-direction. Is it possible to get the forces in other directions, namely r and theta?

Could anyone help with this please.

Hi Nish.

I think the resulting forces on a distinct patch are printed in the output file and if you use cylindrical coordinates, the resulting forces will be in the X, R and Theta directions. Converting the initial geometry should give the X, R and Theta directions as the reference system and therebye the right directions in the output.
