Redefine Local Coordinate System

To define new local coordinate system, we can use ANSYS's command called, "LOCAL". The LOCAL command takes in 8 parameters.

The first parameter is the reference number assigned to this coordinate system. The second parameter specifies the coordinate system type. (0 is for cartesian coordinate). The third to fifth parameters are location of the origin of new coordinate system (*x,*y,*z). The sixth to eighth parameters are the rotation about (z,x,y) axes in degrees.

Therefore, by typing in

LOCAL, 11, 0, 0, 0, 0, 0, 0, 15

we manage to define new coordinate system to have origin at (0,0,0)

with 15 degree rotation about y axis.

Also, if one prefers using the GUI, go to

WorkPlane --> local Coordinate Systems --> Create Local CS --> At Specified Loc

Then select the location where you want the origin of new coordinate to

be. Or just type 0,0,0. Then input parameters as shown here.

The new coordinate should be defined. If you cannot see the new

coordinate, click on replot.

Also, do not forget to remesh the shaft. To do so, go to

Preprocessor--> Meshing--> Mesh--> Volumes--> Mapped--> 4to6 sided

The next step is to reapply the boundary conditions and loads.
