Facts about the Surface to Surface
contact option:
- This contact formulation is available
for static
studies and nonlinear studies. It prevents interference between the source and
target faces during loading but allows them to move away from each other to form
gaps. For thermal studies, this option is available with the Thermal Resistance
contact type.
- Suitable for complex surfaces that come into contact under general
loading.
- Does not require common mesh nodes between the source and target
faces.
- Allows faces only as source and target entities.
The program selects the candidates for source and target faces internally. They
are defined using the Set 1 and Set 2 entities in the Local Interactions PropertyManager.
- In most cases, it gives more accurate results than the Node to Surface option, but requires more time and
resources.
- Creating a fine mesh in the contact area improves the results for
this option.
- Not recommended when the area of contact between a source face and
target face becomes too small or reduces to a line or point during deformation. In
such cases, use the Node to Surface option
().
