FEA won't run?

[Anonymous]

All,

I can't seem to get FEA to run on this frame assembly.

See CF NG for file.

Any ideas what I've done wrong?

Your model is pretty complicated ( I mean to do FEA with MDT) , MDT's FEA
does not work well even for simple solid block with few cuts and holes...
By the way is there any one out here who has used this FEA successfully ?

Brian,

AMFEA3D is a cool little tool for stress ananlysis. However, the meshing
capability is not as strong as other professional FEA packages. It does not
allow users fine-tuning meshes. Therefore, the model should not contain too
many small curvy faces. AMFEA3D will have problems in meshing Fillets or
chamfers. Actually, the stress analysis results does not make much
difference with or without fillets. I used AutoCAD SOLIDEDIT command to
delete all of the fillets on the model and reapplied constraints. Please go
to customer file area and find a message "To Brian Verboort." Please try the
model and see what you get. I believe AMFEA should work fine.
Let me know if you need more information.

Brian .
Please let us know if you have any success doing FEA with this simplified
solid.
I tried it too but it completed only 3% overall in an hour and hung and
then I had to cancel that...

I used the FEA on a part with several angles a holes... Worked great. One
question, what is the file name of the material database? The ANSI
selection does not list 304 stainless (SAE 30304) and I would like to add
the properties.

You can't, to my knowledge, access that database directly as you can the
.mat file. It must be edited using the vba editor. My system is down
so I can't look to refresh my memory. As I recall you find the material
section in standard parts, then click on edit, and go from there. It
took a little trial and error to figure it out, but I finally was able
to add my own materials. When I finish re-installing MDT I'll be able
to look at it. Maybe someone else has done it. --Billy

Viqar,

No luck with the simplified version either.

Looks like I'll have to abandon the effort.

Thanks to all who tried.

Best regards,

I have been able to get usable results, but it has taken quite awhile.
Partly MDT, but mostly that I am weak in that kind of engineering. It
seems to work okay if you simplify, remove fillets and complex curves.
I will look at the file, but right now I'm trying to solve my amstitch
problem(subject). Take a look if you have time.
