i have one model with 100 surface contact, i set this contacts(this spent very time).
i need change model with inventor,but i can't save contact situation for after edit model.
please help me about save contact situation for fem file in simulation multiphysics?
For your model with more than 100 contact, if you are using MES, you might try to use selection group to simplify the contact definition.

There is no command to save the contact information. So the best that can be done is to find a way to work with the capabilities that the software has. I have some questions for you that may help someone to provide an answer.
Hi 522192,
For question 2, you can use a temperature difference -- thermal expansion -- to get the pre-strain that you want. strain = dL/L = alpha*dTemp. However you apply the temperature, just be careful that those temperatures do not cause the mating parts to expand or contract, too.
I cannot provide much insight for question 3 since most of those questions need a response from Autodesk.
How can any software calculate the natural frequency when it contains contact? By definition, there are no loads in a natural frequency analysis. With no loads, there are no displacements. With no displacements, how does the software know how much and where the contact is occurring?
I certainly hope you will take all of the answers that you receive through this discussion group and add them to the wiki help. If everyone did that, the Help would be the best in the world. I know from personal experience that writers can only write about what they know or what they think of; they cannot write about something they have never thought of. 😉
