Re: Press fit check box

I believe that the "for press fit, ignore interpenetrations larger than:" is only for geometry that is initial interference. If the geometry is not in interference/has a gap, then this feature ignored. I ran four test cases to confirm this:

1. 1/4-symmetry pin and plate w/ hole with an initial interference of 0.05 in and "ignore interpenetrations larger than:" set to 0 in.
2. 1/4-symmetry pin and plate w/ hole with an initial interference of 0.05 in and "ignore interpenetrations larger than:" set to 0.049 in.
3. 1/4-symmetry pin and plate w/ hole with an initial interference of 0.05 in and "ignore interpenetrations larger than:" set to 0.05 in.
4. 1/4-symmetry pin and plate w/ hole with an initial gap of 0.05 in and "ignore interpenetrations larger than:" set to 0 in. A thermal load was applied to the plate to shrink in onto the pin.

The results I got were:

1. Interpenetration remained; no contact stresses developed.
2. Interpenetration remained; no contact stresses developed.
3. Interpenetration removed; contact stresses developed.
4. Gap removed; contact stresses developed.

Were you having analyses fail if you didn't modify the interpenetration value or uncheck the box?
