As an aid for structural calculations of planar components, RFEM provides the option to display the FE mesh quality.
Extended Display of Strains in RFEM
Display extended strains of members, surfaces and solids (e.g. important principal strains, equivalent total strains, etc.) in the Project Navigator - Results in RFEM as well as in Table 4.0.
For example, you can display governing plastic strains when performing the plastic design of connections with surface elements.
- After activating a layered FE mesh, the axis orientation is automatically reset to the default. How can I keep the defined axes after layering the FE mesh?
-
How can I perform a stability/buckling analysis on a load-bearing structure?
- I have calculated a pre-deformed structure according to the second-order analysis with RF-STABILITY and RF-IMP. Why are the deformations of the CO smaller than the applied pre-deformation?
- I have to dimension a wall bracket (steel brackets). I have modeled it as surface components in RFEM. The question: Which module can be used to calculate these steel brackets?
- I obtain different results when comparing the deformation analysis in the RF‑CONCRETE add-on modules and another calculation program. What could be the reason for this?
- During the plausibility check, I get an error message saying that the surface opposite from the contact surface cannot be located. How can I fix this?
- What is the best way to consider steel fiber concrete in the structural analysis software RFEM?
- How can I deactivate displaying symbols for the FE mesh refinement?
- How do I display some results of all load cases in the printout report, but other results of the selected load cases only?
- Is it also possible to subsequently deactivate the symbols for the FE mesh refinement in an existing graphic in a printout report?
