• ### How can I create the line where two arbitrarily shaped surfaces intersect in space?

The line can be created by means of the intersection. With the shortcut menu, you can retroactively convert the line created by the intersection into a classical line by using the "Convert to line" function.
• ### How can I quickly create a contact solid between two contact surfaces in RFEM?

FAQ 002443 EN Modeling | Structure RFEM

The quickest way to create a contact solid between two planar surfaces is to use the function "Create Solid by Contact." Select both contact surfaces and select the corresponding function in the shortcut menu (see Figure 01).

The program automatically creates a contact solid including all boundary surfaces and openings in the solid. All you have to do is define the contact properties in the settings for the contact solid (see Figure 02).

• ### Can solids be modeled and statically calculated in RFEM?

FAQ 002423 EN Modeling | Structure RFEM

Naturally, volume elements can also be generated with RFEM. These are above all always useful if it is z. B. is particularly shaped machine components or particularly thick components. Even if an image as a surface element is no longer possible, the image by means of volume elements often offers. As a result of the calculation of solids, we obtain deformations, stresses and distortions.

Other areas of application of volume elements include contact problems. Thus, for example, with a contact volume, the contact conditions of complex connections with the contact properties "failure in pressure" or "failure in tension" for the contact perpendicular to the contact surfaces can be taken into account. Parallel to the surfaces are the properties "Failure if contact with surfaces does not work", "Full power transmission", "Rigid friction", "Rigid friction with limitation", "Elastic friction", Elastic friction with limitation "and" Behavior of the elastic volume "to choose from.

Contact properties between two contact surfaces can also be realized via area approvals (see following general descriptions):

There is already an interesting video from Dlubal Info Day from 14. December 2016 with the topic "Dlubal-Infotag online 2016 - Part 4: Modeling and calculation of volume elements in RFEM "on our homepage :):
