A new powerful stiffness matrix stabilization feature will be present in ADINA 8.2 to stabilize static analyses in the presence of physical rigid body modes. The new stabilization technique can be used with or without the modeling features already available in ADINA. The new technique makes complex analyses much simpler, is fully automatic and does not affect the solution.
The animation shows a very simple metal stamping simulation, used merely for demonstration, where the workpiece is insufficiently supported. The results shown in this animation were obtained using the new stiffness matrix stabilization feature.
