Hi!,

 

I'm planning to use parameter correlation to study the pressure contact between parts when varying CAD parameters. My model has 4 parts, when they are in the nominal values the parts have full contact, but when I use the Parameter Set in the workbench to vary the dimension from the CAD model, a gap or penetration between some parts appears and I get an error when I apply the force cause it doesn't find contact between the parts.

I have tried to assure the contact in the CAD model using constrains but hasn't worked.

I have a restriction so I cannot use adjust to touch as interface treatment. So I have a applied a displacement (at the first strep before applying the force) to assure contact between the parts. I also set the pinball radius, but then I need to manually modify the displacement depending on the dimension of the gap.

Is there a better way to assure contact so I can just modify the parameters and run the simulation from the Parameter set, without having to open the model and change the displacement value. 

 

I will appreciate any advice.

 

Thanks!

What CAD system are you using? Most CAD systems are good at Assembly Mating Constraints. Stay in CAD until you have figured it out.

I'm using SolidWorks.

Keep working in SolidWorks. It has good assembly mating capabilities. I have SolidWorks 2019, though I am not highly skilled at it.
