Difference between Clearance and Contact Interference (Abaqus)

Difference between Clearance and Contact Interference (Abaqus)

Difference between Clearance and Contact Interference (Abaqus)

(OP)
Hi,

Does anyone know the difference between the Clearance card and Contact Interference card in Abaqus ?
It's because I ran a calculation with 2 meshed surfaces which are not strictly parallel.
The Clearance card provides a COPEN equal to the clearance value I specified at the beginning of the calculation, on every nodes of the slave surface.
Instead of the Contact Interference card (without adjust for the contact where I apply the clearance), which provides a variable clearance between my surfaces at the beggining of the calculation, surely due to the initial mesh configuration.

Thanks for the help.

Eric
