Different meshing different results ???
Different meshing different results ???
(OP)
Good morning,
I am tring to meshing the attached geometry using Abaqus. Originally the part come from Inventor. I receive it as a .sat file. It is a filter, loaded only by mechanical loads on the nozzle.
I am speaking of tridimensional solid geometry. If I use tets no problem, it will be automatically mesh and the solver show me around 150 Mpa.
If I wont to use brick it is more complicated. Before I have to split geometry and after apply different size on each zone. I mesh it ( but model become very heavy ) but the risult is completely different 650 Mpa.
I think this solution it is wrong because displacement are about 150 mm and this is impossible.
The main point now is : I wont use brick because they are better to solve stress problems but in this case it appear not correct / no good. I don't understand where I do mistake.
Any suggestion?
Thanks

Also, different meshing schemes will definitely give you different results. Be careful with tets. Unless you run convergence tests, you can never be sure of your result.
