Abaqus cylindrical

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.

My question is what is to be done to get the nodal coordinate in cylindarical form (R, theta, Z) or is there any transformation command in abaqus that i can apply.


dear jawad,


I`m working on simulation of arc welding process that I use Goldak double ellipsoid, I must use ABAQUS for simulation and now I written DFLUX subroutine but I don`t know how I can apply or attach this subroutine to my model in ABAQUS.

please help me to apply this DFLUX subroutine to ABAQUS.

Thanks and Best Regards.

please send your helps to my mail:
