Thanks for the information. I was getting singularites due to the very thin shell (0.001 inch thick) that I was using to coat the solids (as you mentioned).
Hi,
I'm shell coating solid finite element geometry (parabolic tetrahedron elements)to do some correlation work with strain gage test data. Is there a good rule of thumb for what thickness the thin-shell element should be when you're trying to simulate a strain gage? What experiences have you...
Need more details. When you import the iges file I'm assuming you checked to see if your part was a closed volume. If it's not a closed volume, the mesh won't generate. You can check to see if you have a valid closed volume by doing a properties check (Ixx Icon). Then if you hit the...
I got a model from another department and they used Hypermesh to model their system. They also used metric units. When I bring this into I-DEAS with English units everything is out of scale. Is there anything I can do on the I-DEAS end to convert this to English? Thanks.
Hello,
I am trying to model the rider and passanger on a full-vehicle motorcycle FE model. I am representing them as lumped masses at their appropriate c.g.'s and want to hook them up to the vehicle so that during acceleration loading (braking), their masses will load the vehicle appropriatly...
Thanks for the reply toothroot, but I'm a little confused. In my experience, when you hook up a lumped mass with rigid bars from the handlebars to the footboards (a long span of distance) you artificially stiffen the structure unless you have soft springs between the rigids and whatever they...

Jules,
I think I know what your problem is. Sorry if I'm wrong, but I think you meshed two seperate parts that were not "joined". This means you have two parts and two fems, but they are seperate from eachother. If I'm going to do a contact problem using surface definition, I always...
