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!
