I try to build a model containing contact and then calculate the the natural frquencies of this model in NX 8.5.2.
But simply activate a simulation object for the desired contact does not work.
My parts does not interact.
I try to analyze a model with two solid cylinders put into each other and connected via contact with penetration offset. But both cylinders have uncoupled eigenmodes.
What is the correct method to do such a simulation?
I could not find answers for this in NX help material.
Any suggestion will help.
With best regard,
Go to Solution.
I found the solution:
- I have to build a pre loadcase in solution set 103 of step type "Subcase - Statics" first and
- after that I can build the step "Subcase - Eigenvalue Method".
In this case also the keyword STATSUB can be found in NX-Dat-File as described in all Help manuals.
SUBCASE 1LABEL = Subcase - Statics 1...
SUBCASE 2LABEL = Subcase - Eigenvalue Method 1STATSUB = 1METHOD = 102
Keep this in mind...
