Several postdoctoral and PhD research positions are currently open in the Advanced Computational Technology (ACT) group at the University of Pittsburgh for the following research projects in the multidisciplinary areas of computational nanomechanics, bio-nanotechnology, renewable energy, and nanomedicine:

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.

I'm working on the numerical solution of the mixed problem in lubricated contacts. Does anyone know if the lubricant equation (Reynolds one) was never solved for film thickness instead of pressure (like actually is done with MGMI techniques) in some pubblication?
