Hi Charudatta,

Thanks for your quick response. Our observation is that in our introductory seminars for discovery, we mostly had at least one participant that showed interest in something like a snap fit problem. Most of the time, those folks are designers, not engineers. Currently, they do not have a real chance with discovery to solve this, even with extensive training from us due to the almost complete lack of debugging capability . Please discuss with development wether we want to enable this type of user to solve nonlinear contact problems inside Discovery Analyze. That would require some solver feedback in the Analyze GUI. Alternatively, we would point them towards Mechanical in Workbench, which is clearly able to solve this kind of problem. We at CADFEM are in favour of enabling designers to solve at least some basic nonlinear problems without having to switch the GUI, since we train them to use Discovery. kind regards, Klaus
