RFEM 5 | Modeling Quarter-Circular Ring with Variable Thickness

How can I model a surface as a quarter-circular ring with variable thickness from the inside to the outside?

Answer:

In the case of surfaces with variable thickness, the plane consists of three nodes. The result is a wedge, not a cone, as desired. Therefore, we recommend dividing the quarter-circular ring into separate uniform surface segments:

  • Divide the inner arc line using n intermediate nodes.
  • Divide the outer arc line using n intermediate nodes.
  • Add individual lines, delete the original surface, and redefine the individual surface segments.

or

  • Add individual lines, divide the original surface using integrated lines.
  • Define variable thickness as desired for each individual segment.
