  1. Ideal Gas in Structural Analysis

    In theory, an ideal gas consists of freely moving mass particles without extension in a volume space. In this space, each particle moves at a speed in one direction. The collision of one particle with another particle or the volume limitations lead to a deflection and a change in the speed of the particles.

  2. Setting Axis System of Solid

    The stresses in a solid can be evaluated in RFEM 5 relative to the global as well as to the local axis system. The local x- or y‑axis of the solid can be oriented parallel to the axes of a boundary surface, a line, a surface, or in the direction of a user‑defined coordinate system.

  3. Defining Clipping Plane

    The “Clipping Plane” function allows you to define any section through the model. With this function, you turn the part before the plane off so that you can see into the solid element or the intersection. Since it is possible to shift this plane any way you like, this function helps you follow the distribution of internal forces or stresses.
