I'd like to 2nd this request. These are terrible. If you can't get rid of them is there a way to make them at least not be the priority when mousing over them?
Hi Illini,
Our company has had problem like this in the past. One of the solutions we have used is spherical bushings. See here for examples.

These bearings/bushings allow for radial tolerance in your assembly...
I would also add that if you really are looking at any type of large deformation you really need to run this as a non-linear model. You also need to look at how you are setting up the material properties and what material model you are using. Plastics and rubbers don't behave the way metals do.
Hi Marty,
Welds in simulation is always a problem. Mostly because you have issues with actual welds vs what we model. I remembered that Solidworks used to have a set of Simulation Tutorials by Vince Adams. I'll attempt to attach the weld one here. The whole series is a great read if you can...
Hi Marty,
Sorry you are having issues. My best guess at the problem you are having is that however you cut the cylinder is not planar. So that the faces you are trying to select as symmetry are not actually co-planar. You should be able to use the measure command and select the faces to...
Here is a sample model set I made based on your geometry. I'm still not 100% clear on how your inner part relates to your outer part. Note that I'm fixing both models and am using draft mesh for speed. Take a look and let me know if this shows some insight into what you could possibly do...
Sure you can use no-penetration in non-linear. Just look at the tutorial example Nonlinear Contact Analysis of a Pipe Holder. Anytime you are looking at large deflection like this you have to use non-linear. Remember that non-linear does not exclusively mean below yield. Let me work up an...
Hi Abe. I'm having a hard time understanding your boundary conditions. How is the inner steel piece attached to the AL piece in real life? Would be happy to help but I need to understand the setup a little more.
As far as global settings go you want to use Allow Penetration and then...
You could create a zero offset surface of your vessel on either the inside or outside face and analyze that. This might be easier than defining the faces in Simulation.
jamiddel,
One method that was not brought up here is one that use regularly. Here are the steps.
1) Have the PEM and the assy open.
2) Tile the screen so you can see both viewports.
3) Adjust your assy view so the hole you want to mate to is visible.
4) On the PEM select an edge that will...

1. Right click on your frequency study and choose properties. You can adjust the # of frequencies there.
2. I'm not sure what error you are having. You didn't actually hide the remote mass symbol did you?
3. Can you clarify your question? If you are talking about...
Before you even go that far just do two blocks face to face. Make sure they are propery restrainted and that the contact faces to not match line to line. Make on face larger than the other. Try that and see if you still have failure.
