  Hi Seniors, I'm new to LS and I tried wb extension for LS DYNA to set up 2d material cutting simulation (like I did for wb autodyn explicit, and it worked in autodyn explicit) but here, the case is "hilarious". Tool moves through the workpiece with out even touching it (shown in photo).

  LS-DYNA System in Workbench won't write 2D contact keywords. You have to export the K file from Workbench, edit the K file manually by adding _2D to the Contact keywords in the K file. The 2D contact keywords could be *CONTACT_2D_AUTOMATIC_SINGLE_SURFACE or *CONTACT_2D_AUTOMATIC_SURFACE_TO_SURFACE.nFinally, you need to run the modified K file using MAPDL Product Launcher and post-process the results either in LS-PrePost or in WB LS-DYNA system after reading the results back to the WB system.n
