Dear all,

I am trying to learn how to use of Cosmosmotion and I find a problem
in tutorial3 valvecam.
When I open the file tutorial3_valvecam_with_results.sldasm, the
simulation is running well until the full simulation time of 0.03 sec.
The simulation shows no interference. Just fine !
The problem is that when I cancel the results and restart the
simulation (without any change), it stops after 0.012 sec, and I can
see that the camshaft material interfers with the rocker material.
I really don't understand why. If somebody could do the same trial I
would be interested in his results. Any idea welcome.
Thanks in advance and best regards,

Francis

Fancis,

The problem may be that when trying to restart, you are in fact in an
"interference" position. There is a checkbox for "Stop at
interference", so this may be coming into play.

Thank you Eddie for your comment.
I don't think that this maybe the reason because I restart from
original position at time 0. During restart, from time 0 to 0.012, the
motion is ok.
I would rather suspect some problem in the contact between the
camshaft and the rocker but I really don't understand why the
simulation is going well first time and not after restart.
If you have some time, I would appreciate your trial with this
tutorial3.
Thanks,
Francis

No Cosmos Motion user ?
Any other forum for Cosmos Motion ?
Thanks for advise,

You could try the Solidworks corporate forum at https://forum.solidworks.com..
There is an Animation/COSMOS Motion group there.
