Trimming 1

Dear All,

How can we trim a surface.

Cut it by either using a flat plane described offset from the surface or if the surface is flat then use that.

Dear Corus,

I have cut the surfaces (a quarter of three-phase cylinder) however, when I run the program I recive the zero pivot warning that seems I didn't define the surfaces correctly. I would be appreciated if you could help me.

Meanwhile, my model is a quarter of three-phase model with different elastic modulus and also at one end fixed and at the other end tensile load.

Zero pivot has nothing to do with how you have defined the surfaces. This usually refers to a lack of restraint to the model. Check your restraints and visualise how your model could either move freely in space or rotate in space whether or not a load is being applied in that particular direction.

Dear Corus,

Thanks for your attention.

I have changed D.O.F for several times but, my model still aborted and no result.

I explain my model in previous e.mail. Would you please run this model at your convenient time and see the result.

Sorry saeed but I can't run your model as I'm a little busy right now. Try putting some pictures of the model on to a web-site showing the mesh, and showing the restraints. The more the better. You can use netomat.net for free to post pictures. Others have used other similar sites for displaying pictures.
