  1. hi everybody a basic question! has anyone ever modeled rigid to flexible body contact(not just a single point to deformable surface one) for multi body dynamics analysis in hypermesh or motionview? if so,could you please help me with how to do that! im really stock in that and i cant find any example or tutorial about the subject! here is the error i constantly get: "Parameter U=0.618718 goes out of intended range (-0.5, 0.5)! Abnormal return from processing model! Error encountered in analysis! This error occurs in module "mbddrv"."

  3. hi everybody! sorry that the post is a bit long! im trying to model the contact between the piston pin and the piston end of a connecting rod in an vehicle piston assembly,that of course the rod is flexible and the pin is rigid!it's an mbd analysis! i define a "mbcntds" contact witch has a node-set on rigid body as the master and a set on flex body with "mbdsrf" card as the slave surface and the normal contact type is poisson! when i run the solver, after the flex body generation in radioss it gives an error in mosionsolve as follows! "Parameter U=0.618718 goes out of intended range (-0.5, 0.5)! Abnormal return from processing model! Error encountered in analysis! This error occurs in module "mbddrv"." i guess "U" might be related to the parametric definition of a surface or curve! but i dont know why this error occurs and how one can possibly change the range! i need to do the modeling in hypermesh not motionview cause i want to perform an optimization on it after! there was no tutorial or example in hyperworks help for defining such a contact in hypermesh enviroment! i would be so thankful if you can help me!
