Surface to Surface Contact

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 (Local Interactions PropertyManager > Advanced).
  • Surface to Surface formulation is used for contact interactions when you select the Arc Length Control method.
