In addition to the "Mesh Refinement" and "Specific Direction" options for solids, you can also activate the "Grid for Results" option, which allows for organizing grid points in the solid space. Among other things, the center of gravity can be set as the origin. There is also the option to activate or deactivate the visibility of the grid for numerical results in "Navigator – Display" under Basic Objects.
Convince yourself by the powerful calculation kernel, its optimized networking and support of multi-core processor technology. This provides you with the advantages, such as 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. Thus, you can calculate even large systems with the fast direct solver. If you need to calculate multiple load combinations in your models, the program initiates several solvers in parallel (one per core). Each solver then calculates a load combination, which improves the core utilization. You can systematically follow the development of the deformation displayed in a diagram during the calculation, and thus precisely evaluate the convergence behavior.
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.
