I'm currently searching for the shape of the Streamlines and deduce the shape of the nugget zone and TMAZ, from the simulation of this flow (after the pin passing). For the thermal part, I use the Colegrove model [1] in my simulations.
Thank you.

I suggest you the following paper that presents a moving mesh technique to simulate the material flow during friction stir welding in an eulerian formalism:
E. Feulvarch, J.C. Roux, J.M. Bergheau, « A simple and robust moving mesh technique for the finite element simulation of Friction Stir Welding », Journal of Computational and Applied Mathematics, Vol. 246, 2013, doi: 10.1016/j.cam.2012.07.013, pp. 269-277.
Thank you very much (Mr J. Bergheau ) for your help and your paper ...
Best regards.
