3d modeling truck counterframe

[valeriom]

Hello, everyone! I'm doing the internship in a tipping company and I should make a 3d model of a truck counterframe.
the software I'm using is ansys workbench.
I'm at first with such software, and obviously I have problems: I imported the geometry from solid edge into the workbench, I put all the contacts to simulate welds, but when I go to make mesh I have serious problems: it makes me horrible!!! (I press that it is 6 days that I touch and retouch the parameters of mesh in the workbench).
with my professor (who has never used ansys) we have come to conclusion that for mesh perhaps you should do it in ansys icem cfd, which gives more possibility of choice of elements and their arrangement on faces and lines.
is it correct as reasoning? Why can't I do all the modeling from the workbench?
Is there a pretty fast method that allows me to make a mesh 3d "decent"?
I thank all those who will respond!

Bye!
Maybe there was a way to make good mesh with little time! Actually at the moment it is not so...you have to intervene heavily on the geometry by cutting it and ritalgiandola until with create a set of prisms that can be meshati with hexaedri. At least in the most interesting parts. good and fast mesh is obtained if you have surface elements, shell to understand us.

good work,

Hello and thank you for the answer!
Yes, as you say, geometry is to be fixed... But now I have to learn how to use the program, and I have to understand how he thinks.
today I managed to create a mesh in icem cfd, which in first approximation is not bad. Obviously then it is better to define (type finish faces and curves of greater interest, I saw that such a thing can be done...).
but how do I take this mesh built in icem and put it in the workbench? Is there anything to do with fe modeller?
I am at the beginning, sorry for the banality of my questions:

icem for the moment is out of the wb speech, but you could send mesh into the classic.
cmq icem is not exactly the maximum of simplicity, I do not think that alone you will manage to go beyond a tetrahedric octree mesh.

I understand... so it does not interface with wb...
If I can ask you something else:
I have a 32-bit windows xp system. Is it possible that ansys doesn't work with a mesh enough push in the wb? continues to give me memory errors, but virtual memory is in sufficient quantities. I read in the help something about contiguous memory blocks... can be windows 32 the problem?
because of these problems I am stuck with work!! I don't know what fish you want.

Thanks again for the answers you gave me!

Hi.
Unfortunately your hypotheses are founded, when you go up with the mesh the memory gets exhausted and win32 does not make it after the 1,2giga of allocata ram throws you out. then either reduce the size of the mesh, or move to a 64bit system or install us linux 32 that does not have these limits. or break the model in many submodels, but here the matter is complicated.

Thank you, you were very helpful! I'll see what I can do to finish the job... I'm seriously thinking of renting an eheh workstation...

Thank you again!
