WebSingularity elimination factor (0-1) Sets stiffness singularity elimination factor (normal solution is set to 1; if less than 1.0, the program modifies stiffness terms causing … Mathematically, the solver uses matrices to represent the elastic field (displacements of the elements). When a highly localized load is applied, the gradients of the displacement vectors begin to diverge, causing the roots of the matrices to go to infinity. For a simplified explanation, see the … See more Singularities are usually seen at points, edges, or reentrant corners. Reentrant corners are interior corners, with angles pointing into the part. The high-stress concentrations are usually seen near 90-degree corners, but … See more Singularities are idealization errors that you can avoid by understanding the assumptions made within the software. First, confirm singularities using a trend tracker graph and increasingly finer mesh. Then adjust your … See more Think of the common case of singularities created on interior corners. In software, that corner is perfectly sharp. In real life, there will always be a slight bend. Also, the part may deform … See more You now understand singularities and have determined you have a singularity in your part. If you choose to ignore your singularity skip to the bottom two bullets in this list. If you want to fix it, you must adjust your part or … See more

WebApr 24, 2014 · The Nonlinear Autostepping Option. In general, the Automatic (autostepping) option is recommended. This is because the optimal time step size may vary throughout the solution process depending on local … WebThe hinge is fixed and the rod is an advanced fixture using reference geometry that move it forward into the hinge. Solution failure in a Step>1, it could be due to: The solution may be at a buckling or limit point, i.e., displacements grow large under constant forces.

WebApr 28, 2011 · In terms of the mesh, convergence refers to the process where results hone in on trustworthy values, independent of mesh factors that might be distorting the truth. A mesh that is too coarse, where elements are too large around small geometry, will not have the detail necessary to display accurate results- often underestimating the stresses you ... chinese meatballs recipe
