Hello,

I'm trying to model a moving volumetric heat source on a cylinder path.

The code isn't working well. The source is moving along the perimeter, but something is wrong.

The source should be moving on a circumference in the x-y plane.

The input provided doesn't have any select commands to select elements within a certain angle. Typically a cylindrical coordinate system would be used to select nodes within a certain angle and then the elements attached to those nodes could be selected:
csys,12 ! Activate APDL cylindrical coord system number 12
nsel,s,loc,y,theta1,theta2 ! Increment theta1 and theta2 in the do-loop
esln,s,1 ! select elements with all nodes selected
! apply loads
