model works with identity pairs but not with contact pairs
Posted Oct 6, 2012, 1:59 PM EDT Version 4.3 3 Replies
The model with identity pairs works OK, see first attached .mph file. However, when I put in contact pairs in the boundaries shown in these models (i.e., at the interface of the nylon and the Ti cap, and at the interface between the metal "ring" and the nylon), the model does not work; see last attached .mph file. Just FYI, this model works fine when I simply use a "union" command to construct the entire model, e.g., with all interfaces connected. But I would like to test the effects of friction at the interfaces noted, hence the attempts with assembly and contact pairs, etc.
I get various error messages depending on how I tweak the model, including errors such as "segmented solver steps do not include all components", etc. Sometimes there is a convergence error.
Thanks in advance.
