Missing Reference Point
Missing Reference Point
(OP)
I am trying to run an analysis, but I recieve an error message when I submit telling me that the rigid part instances back plate does not have a reference point. However I have defined a reference point (RP-2) to this part with boundary condtions. I have uploaded the cae file. Any input would be much appreciated.
Thanks
Thanks





RE: Missing Reference Point
Why do you have 2 rigid bodies? There will be no deformation.
You are holding the one face of the plate and also applying a pressure to it. The constraint will act as a sink for the load.
When my current job's complete I can try to make these changes and run it here but that might be a while.
I hope this helps.

Also, they seem to model the problem in explicit and use orphan meshing. Any reasons for this?
Also, sorry does RBM mean Rigid Body motion? Why would we need stablization if we already defined something as a Rigid Body?
Thanks again

This is probably to reduce the file size. I almost always import geometry unless it is simple like a plane or a sphere.
Yup. The break pad could translate in the U1 direction if the contact was not occurring. This removes the issue of an infinitely small force causing an infinite displacement. I use is by default in contact problems and then check if the energies are excessive.
I hope this helps.
