Adjusting Length of Guidelines in Grid

When modeling and designing glass panes in RF-GLASS, you have two different options for the FE mesh settings.

You can make various settings in order to achieve a clearly‑arranged display of the result values. For example, some users may not want the white background in text bubbles. You can adjust the background in "Display Properties" using the Transparent and Background color option.

In RF-/FOUNDATION Pro, the user can freely select the proportion of the relieving soil pressure by means of the factor k_red.

If the check box 'Number of load increments' is deactivated, the number of load increments will be determined automatically in RFEM to solve nonlinear tasks efficiently.

The method used is based on a heuristic algorithm.

With this function, it is possible to refine the FE mesh on surfaces automatically. The mesh refinement is gradual. In each step, the FE mesh is recreated based on an error comparison of the results in the previous calculation step. The numerical error is evaluated from the results of surface elements and is based on the energy formulation of Zienkiewicz-Zhu.

The error evaluation is carried out for a linear static analysis. We select a load case (or load combination) for which the FE mesh is generated. The FE mesh is then used for all calculations.

The equation solver includes an optimized FE mesh generator and supports the latest multi-core processor and 64-bit technology. It enables parallel calculations of linear load cases and load combinations using several processors without additional demands on the RAM: The stiffness matrix only has to be created once. The 64-bit technology and the enhanced RAM options allow for calculation of complex structural systems using the fast and direct equation solver.

The development of the deformation is displayed in a diagram during the calculation. This way, you can easily evaluate the convergence behavior.
