A robust and efficient strategy is proposed to simulate mechanical problems involving cohesive fractures. This class of problems is characterized by a global structural behavior that is strongly affected by localized non-linearities at relatively small-sized critical regions. The proposed approach is ...
3.3 Sources of parasitic oscillations and solutions An example of parasitic oscillations in a solution computed using the FFT-based numerical method is shown in Fig. 22. Such oscillations are a major issue for the fracture mechanics problems which are targeted in the present section. Sign in to ...
Such mesh network, which nodes are all connected to each other, is known as a “fully connected network”: the wired ones have the advantages of reliability and security: the problems in a cable affect only two nodes attached to it. Usually in such networks the number of cables, and so ...
Note that spurious responses of various kinds appear in all DE models, for example [74], and elimination of these spurious solutions is currently being studied.

A good mesh is always associated with the physics.When you change your boundary conditions, or change your load conditions, or change analysis types, or change flow models, the good mesh (with the identical geometry) may turn to be bad mesh. ...
Common mesh problems and solutionsExtraneous areas on stairs and rampsThe automatic generation system tends to build areas that hang off the side of stairs and ramps. These should be removed to force the bots to take the stairs or ramp straight-on. ...
?This creates another problem in that a huge number of reduced problems exist with solutions that cannot usually be found by a gradient-based optimizer in the full design space. ? Stress constraints for a partial domain of the structure are not allowed because they often create an ill-posed ...
and it is important to modify the mesh to eliminate them because they generate equation systems that are extremely difficult to solve and possibly have nonphysical solutions. An element with negative volume has a quality that is zero or less than zero. An example of an inverted hexahedra is sh...
Singular topology refers to the problem associated with the conditional nature of stress constraints, i.e. the stress constraint of an element disappears when the element vanishes. This creates another problem in that a huge number of reduced problems exist with solutions that cannot usually be ...
No. You can wire any satellite Deco to the Deco unit(s) that you want to use with the Ethernet Backhaul feature, and other units can be connected via the Mesh Wi-Fi backhaul, if desired, allowing you to mix and match your backhaul preferences. In the example below, the Ethernet Backhau...
