continuous mesh problems also with simple parts in simulation express: aid

[reggio]

hi, I often fail to use express simultation
every time the message is "problem in creating mesh in .." at that point modifies or eliminates that incriminating workmanship and the mesh problem moves to the previous workmanship and so on until it arrives at the white sheet ...

the strange is that sometimes simultation express gives correct results even with moderately more complex parts ...I therefore wanted to understand whether there are "trucks" or anything to deal with the verification.at the moment we realized that:
- zero-measured machining can create problems
- sheets are more skeptical than solids (this pushes us and redesigns the sheet every time )
- having sw intermediate we can only work parts but in general it seems that the assemblies rise problems regardless therefore to avoid in simultation express
- avoid peeling
- ...

the attached model (sw2016) is of the type not particularly complex but very... rognose ...

suggestions, opinions and aids sought ...

all that is not a simple and proportioned solid, with variations of homogeneous sections does not suit the standard mesh.
electro-welded carpenters, plates with holes, thin and shaped pieces etc. need mesh based on curvature and not congruent.

Hello and thank you

electro-welded carpenters, plates with holes, thin and shaped pieces etc. need mesh based on curvature and not congruent.

So you tell me that my example fails because it is part of this second category and that I need a "mesh based on curvature and not congruent"?

what it means "mesh based on curvature and not congruent" and above all, how do I get it to be able to verify also these "more complex" parts?

You do it with the paid version. non-congruent mesh adapts to contiguous and non-homogeneous geometries, so do not collect.
Mesh based on curvature is not normal solid but varies with small and strange geometries.

? I don't follow you, what does it mean for a fee? there is no free sw version ...
... or are you telling me that sw dogs have both the express simultation version inserted in sw prof, one in premium sw and also a re-payment?

However, for the moment, we are redesigning again the profile sent (the original is in several parts of sheet so we had already redesigned simplifying and joining in one part) starting from full and emptying ... it seems that simultation express digests it much better, at least for now ...
. we are adding a piece at a time and testing each addition if the pattern is verified again or if it gives mesh errors ...

with xpress you do little because it serves to swallow you to the premium where the fem analysis makes you complete static. then if of the symulatio take the advanced package do dynamic fem etc...

... in fact sw really swallowed me...
I will not buy nor renew anything for years, even under torture
