static FEA problems! anyone can help?
(OP)
Hi all, i'm actually modeling a cooling tower and i'm facing bugs during FEA analysis. the one which is slowing me down is the "undefined material" error. i have no idea of what that means...
i have some more clues to give:
- material definition is not the problem as i changed my brand new steel to the default one and the problem didn't solve.
- material is defined for every component of the assembly
- the model ran successfully a FEA in the early morning, started giving problems after.
- the meshing runs perfectly for all components, even for those with mesh control.
if someone could spare help or experience sharing would be simply great, actually my solution is to start another study from zero
thanx all

@kellnerp: the entire assembly with single parts attached is like 80MB and is half italian half english as i put the language pack after i started. don't know how of use it can be, but if u want me to send it it's fine
RE: static FEA problems! anyone can help?
Italian doesn't bother me, I can figure out technical language pretty quick.

Look in options for Simulation. Somewhere there should be an option to export the model.

RE: static FEA problems! anyone can help?
by the way, thanx for your time
RE: static FEA problems! anyone can help?
Is there an option to export the mesh?
Just looking at this, why not do it as a shell mesh? It would be a lot more efficient and accurate at run time.

RE: static FEA problems! anyone can help?
however, the problem of the material undefined seem to be tied to cylindrical geometry which appears harder to elaborate even if meshed
btw, can't find a way to export the mesh
RE: static FEA problems! anyone can help?
You will have to pardon me, I don't have the latest versions of Simulation, but what I do have goes back a few years. It may also be that they removed the functionality.

simulation file - .geo
ANSYS file - .ans
NASTRAN file - .dat
ABAQUS file - .inp
Patran neutral file - .neu
IDEAS universal file - .unv
Exodus file - .txt
i also got an options regarding offset of nodes, it makes me write 2 numbers.
don't excuse you on anything, you are helping a lot
don't like signature that much
RE: static FEA problems! anyone can help?
If they ask for node and element offets then why not give it a small number like 10 for both?
Maybe you can do a screen capture of the dialog box (window) and include it here.

RE: static FEA problems! anyone can help?
this assembly is two part composed, the bottom and the body. as they get analyzed well when they are alone, i guess the problem is when they are together as it happens now. so i gotta focus on how they are mated. or maybe i can analyze them individually

Try that. Should give a .geo file with node and element specifications.

RE: static FEA problems! anyone can help?
i'll let you have the .geo file asap if u still want it
still thanks for the kindness and the availability of the help

Sorry for misspelling esporta.
