solidworks simulation

[africagia]

Hi, I wanted to ask you a question about solidworks simulation. when you create the mesh, leaving as standard mesh parameters and clicking on "azzera" in order to choose by default the density of the mesh, the standard mesh that the software creates is already at convergence or should I worry about inflating the mesh until it reaches convergence? thanks for the answers.
greetings

humm the mesh to convergence? I think it's the method of calculation that comes to convergence. If it does not come, it would continue to infinity but there is the threshold of maximum iterative cycles. It may be that mesh is not an end to sufficiency or that there are discontinuities or singular points, so after failure you choose the use of non-congruent mesh.

I said: if I make mesh in the standard way do I get realistic results? or, if I do more than mesh, than the standard way, do I get other results that come closer to the real ones? until, at some point, even if you do more inflate the results do not change.

This is how it works. you take an ever smaller unitary portion almost infinitesimal....so at some point you will get stable values even by infixing mesh.

You said well "realistic" not real. However often and willingly there is no need to impose the mesh which causes only long calculation timing.

remember that on all reports of all fem modelers it is written not to use the values obtained as a 100% trusted source. in fact depends on many factors the result of a good fem. therefore the concept of "more real" depends on many factors, not only on the infitting of the mesh, which as I repeat is not strictly bound mesh fine=real result.

Hi.
for static studies there is the "p-adactive" mode (it is found among the properties of the study), activating which the software infixes the mesh where "it feels appropriate" and repeats the calculation until a "certain" stability of the results is reached... If you're looking for "adaptive methods" in the help, it explains better than I did!
