i am not familiar with contact set in simulation.i have tried to do simulation without contact set.but i failed to get correct result.
Pictures? Just what are you trying to accomplish?
By default bonded (global) contact is set up on an assembly. This may lead to you not getting the desired results.
A better way to figure out what you want to make in contact is using automatically find contact sets and choosing the ones you want to keep. This can be found under contact sets, see image below.
As you can see by selecting the whole assembly in the components box and clicking find contacts it populates all possible contacts by pressing the + button it adds the contact with the type specified below (mine is no pen) if you press the x it gets removed from the list.
That's fine if you only have a few parts and not so many contact surfaces. Sometimes we work w/ 100+ parts w/ multiple surfaces and your technique is not feasible.
Better to know what you want and focus on those particular areas.
If you have lots of possible connections it is possible to select a minimum of 2 components and find the connections between the two and do this multiple times on multiple components. I agree it can become long winded with large assemblies with lots of contacts but it does take some of the click intensity out of the problem.
In addition If you have large amounts of no penetration contacts this may also lead to very large lead times as the stiffness has to be calculated at each contact so it may be advantageous to make a configuration which has the simplest worst connection. This would lower simulation time and still keep confidence in the results been over cautious. I know this isn't always possible but maybe worth consideration.
In that case I have found it better to select a part and find contact sets w.r.t. the total assembly. Then it is usually not too difficult to weed out the sets you don't need.
Thank you all for your support
