I can't apply contacts between parts due to mesh problems
Hy all,
I have problems with the contact of a CAM in a 3D model, Motionview gives me the next message:
I try to improve the mesh coarseness to the top (10 value), but the mesh is still poor:
I I recive the same message when I try to run simulation.
There are forms to improve better the mesh of the geometry?

I'm sorry you're having trouble with your contact settings. Are you trying to model either of these bodies as flexbodies or are they both rigid? Have you considered using 2D rigid to rigid contacts instead?
Can you attach the model here for review?
Hope this helps!

Hi @GTT Adam , I think that I'm working with rigid bodies.
Attached you can find the file:

Can you please provide the model as a zipped model archive?
(File >> Export >> Model >> Archive Model & Create Zip File)Otherwise the graphics are not sent as well.
Hope this helps!

Yes Adam.
Thanks!

When I run the model, there is no contact issue as you have described. The yellow piston moves the yellow cylinder up as it contacts the cam. The only issue seems to be that one of the pistons (coloured green) is not reacting against anything, so once it encounters the cam it shoots off into space:
I think the only missing entity is a joint between the green piston and the yellow cylinder to complete this model.
Hope this helps!

Hi Adam,
In wich version of MotionView did you run the model?

Ok Adam,
We are using the same version but in my computer it doesn't works.

Please try the following:
- Unzip the archive you just made.
- Open the model in MotionView.
- Reset all of the Global Simulation Settings for Static, Transient, Linear, General, Result, and H3D.
- Simulate the model.
Hope this helps!
