I am currently simulation arc welding process. i have performed plate butt welding using abaqus software. Dflux subroutine was used and the heat source model i used is goldak double ellipsoidal model.
Now i want to apply this technique to the welding of pipes, but currently i am having difficulty with the nodal coordinates. I have defined my glodal CS to cylindrical coordinate system in part and assembly defintion. But after generating the mesh the input file contain nodal coordinates in cartesian coordinates.
