Hi all,

I am trying to implement pre-stress on a hollow cylinder in LS Dyna. I am using the CONTROL_REFERENCE_CONFIGURATION keyword, with settings for the Rausch method and 4 iterations. 

Currently, I have 4 k-files: main.k, set_nodes.k, set_mesh.k and target.k. Set_nodes contains sets of nodes, without their x, y, z coordinates. Set_mesh specifies the elements and target.k contains the coordinates of the nodes.

According to the manual, there should be multiple output files, including iter.guess and iter.algo. When running my simulation, only one single iter.guess file is written, and no iter.algo file. Also, an error reading the iter.guess file is raised.

Do you have any idea what could raise this error, and why only one iteration is performed?

Best,

Babette
