I need some advice on a strange problem:
In NX-MCD you can use collision-bodies in order to define how elements collide with others.
When defining collision-bodies you can set categories to specify which geometry a collision-body should react with and which to ignore.
As a very simplified example, I have attached a MCD-Assembly consisting of two overlapping rigid-bodies (hold in place with fixed-joints) and both with dedicated collision-body.
The two collision-bodies are setup in different categories.
When I run the MCD-simulation, on MOST computers the result is as expected: Both bodies stay fixed as the different categories of the collision-bodies inhibit any reaction.
But on one of our Laptops, a HP Z-Book with a NVIDIA M2000M graphic-card, the behavior is different: Both bodies start to wiggle and move as if the collision-bodies react on each other.
When I deactivate on or both collision-bodies, everything remains fixed.
Has anyone any idea on this?!
Thx in advance!
Solved! Go to Solution.
I should add by myself before others ask for:
After opening an issue at GTAC, I received very promptly the solution
If you intend to use collsion bodies in different categories, EXCEL is mandatory!
