  • Answer

    The fastest way to create a contact volume between two flat surfaces is to use the Create Solid with Contact feature. To do this, select both contact surfaces and select the corresponding function in the context menu (see Figure 1). The program then automatically generates a contact volume including all boundary surfaces and openings in the solid. For this only the contact properties in the settings of the contact volume have to be defined (see picture 2).
  • Answer

    It is of course possible to generate solid elements with RFEM. These are especially important for z. For example, it is useful to use specially shaped machine components or very thick objects, or to render a surface element unimportant. The calculation of solids yields deformations, stresses, and strains.

    Another area of application for solid elements is the mapping of contact properties. With a contact solid, you can, for example, For example, you can model the transmission conditions of connections with the properties "Failure under compression" or "Failure under tension" for the contact perpendicular to the contact surfaces. Parallel to the surfaces, there are the properties "Failure if contact with surfaces does not work", "Full force transmission", "Rigid friction", "Rigid friction with limit", "Elastic friction", "Elastic friction with limit" and "Behavior of limit" elastic solid ".

    Contact properties between two contact surfaces can also be realized by using surface releases. They are described in the RFEM manual:

    The modeling with solid elements is also presented in a video of a Dlubal Info Day, which you can find below the links .
