      NODAL_FORCE_GROUP is used to obtain force on selected node set by user. In  my case, I  am getting the force output in one case but in another (more nodes) case  the LS-DYNA stops responging and I have to force quit my interface. Why does this happen? Is there some limit on number of nodes that can be used for force analysis.

      Is there any other way I can obtain force on a Part which I am using in impact analysis. 

      Please share your knowledge with me.

      There is no limit on number of nodes. LS-DYNA stops responding while running or the post-processor? Maybe try plotting from both binout or ascii files. If using LSPP, try a newer version. 

      Please see here ( for different options for forces.
