I'm currently trying out SimSolid for various types of problems and have found it to be very impressive! I had a question about modelling a spherical joint/ connector. As far as I know, SimSolid currently provides an option of modelling a pin joint between parts and a hinged/spherical support with the ground, but does not provide an option to model a spherical joint. An option to create a spring between 2 parts with translation and rotational stiffness (equivalent to the CBUSH element in OptiStruct) or a ready spherical connector would be great! Is this feature planned to be added in a future release? I'm currently trying to do this by physically modelling a ball and socket geometry and defining a separating/closing contact with very low coefficient of friction between the surfaces. The non-linear solution takes multiple passes to solve (even for a small ball-socket trial problem) with mixed results. Would really appreciate it if someone could provide an insight on a way to do this.
Long story and potentially many questions in the same post but all related to the same issue and I ned help! I can't seem to understand how my kjoint2 spherical connection between 2 RBODY is behaving. What I am trying to model is a suspension ball joint in Radioss and I want the rotation to be limited to a certain maximum angle in ANY direction from vertical (creating a conical shaped limit envelop). I created a simple problem to resolve my issues but it doesn't seem to work. I cerated 2 node reference systems in such a way that they move together and that their Z axis is always coaxial. I then limited my kjoint2 in Saz- and Saz+ to ±1 rad but it does not behave as desired. When I plot my TH/spring, I can see that RZ of my spring DOES respect the 1 rad angle limit. But this does not make sense with the visual behavior and the true angle that I can plot in Hyperview that cleary goes over 1 rad. Also Rx and Ry are showing rotation which again does not make sence with the visual behavior. Any help to resolve this is appreciated! Thanks All my simple model files: Radioss_BJ_angle_V19.zip
