Hello Experts,

for my Masterthesis I am simulating some concepts for a fluid connector.

One concept where I am having trouble with the simulation is the following:

A wire clip is inserted in a body and connects the body with a counterpart. To loose the connection the wire clamp needs to spread open. One end of the wire clamp is fixed on the body and the other is outside the body and near to another part. When this other part is getting rotated it catches the end of the wire clamp and the clamp spreads open.

I hope the attached pictures makes it clear.

Hello Maurice,nCould you attach images showing the boundary conditions you have applied (and the regions those boundary conditions are applied to)?nBased on your description above, your boundary conditions seem reasonable. So what issues are you facing? Is your problem not getting solved completely (due to convergence issues or something else) or the problem solves to completion but the results are not what you expected?nIf you could add a few more images showing the boundary conditions and the results or the error you are running into, it would help with the debugging.nnThanks,nSain

Timestepping of Program Controlled = On, with 25 / 10 /1000 (Initial / Minimum / Maximum) is a good rule of thumb.nConsidering using a multi step analysis.nAnalysis like this we often have to hold a part temporarily until the contact resolves, then release it in later timestep. nA Displacement of 0,0,0 can be used as a fixed support, and then disabled or enabled at any later time step.
