Advanced DB Viewer

Advanced DB Viewer (ADBV) is a free high-speed tool for viewing and analyzing ANSYS Mechanical APDL database (.db) files without having to rely on the original ANSYS application.

Twisting The Plate With The Logo

This example demonstrates bilateral torsion of rectangular plates with holes of complicated shape (the logo of our site). The geometrical model was created in SolidWorks and was transformed into a finite element model in ANSYS. Finite-element model consisted of 4344 elements SHELL163, with the element formulation of Fast Co-rotation, and reduced integration scheme. Mesh was generated using algorithms for automatic construction without additional manual corrections.

The deforming load was attached to the finite element model without the need for additional objects. To do this using the tools of choice were created nodal components, located on the end faces of the model. The load in the form of rotation around the axis in mutually opposite directions has been applied to these components for the entire simulation.

The solution was carried out on SMP-system with eight cores. Number of processors was set by the option NUM_PROC = 8 in the configuration file ANSYS. Switching to multi-configuration was carried out by EDRUN, SMP, 1. An additional flag "1" indicates the need for consistency of solution (ie, the difference was eliminated with the solution in the case of one core). Parallel computation enabled the best use of hardware and speed up implementation of the solution in a few times.
 
Processing the simulation results performed in ANSYS postprocessor. With the tools MainMenu-PlotCtrls-Animate-Over Results has been implemented animation deformation process, which allowed the area to provide the critical values of strain and stress.

Qualitative and quantitative characteristics of the physical and mechanical effects on selected stages of loading were carried out using the built-in tools ANSYS.
