    Hi @Shiva Kumar ,

    The RBE2 tool in flexprep is used only if you don't have RBE2's at your desired locations. Looking over your hm file, I already see RBE2's present. Where do you need more RBE2's? Just FYI, if you are trying to use a similar independent node for another rigid element, you will receive an error in regards to that.

    I did take your file, export the solver deck, used that as my input to flexprep, entered in the interface node id's and ran the tool. I was able to produce a flexbody.
