I suppose IDEAS has a similar kernel with UG (though born very differently, they converged to be NX recently), so Drej's advice to use Parasolid format is very valuable: we use UG NX2 and the import of Parasolid files is generally very good (it fails only in some very particular situations, for...
Sure, GBor.
I figure out that one must also look at a theoretic FEM book, where the process of building the element matrices is described. Then, it's just a "mixing" matter btw elasticity theory and FE theory... Not so easy, I fear...
As regards FE theory, I've got a very good book from Prof...
Hi elogesh,
I performed a first run of analyses with a model of a seal for butterfly valve. I used the M-R constants I wrote in my first post: Ansys seems to be clever enough to "sort" the 2 M-R constants so that C1 is always bigger than C2.
Accordance with experimental tests is acceptable but...
ANSYS LS_DYNA is a reference for explicit dynamics.
I personally tested ALGOR Multiphysics with MES, and I found it a really good solution. Not as controllable as ANSYS, but the price is not the same also...
ANSYS' CFD is now CFX, no more Flotran, so you need a license - and the additional...
ANSYS element type BEAM186 is a timoshenko beam. I looked in the help but I didn't find out the matrix of this beam. Anyway, here are some references:
S. Timoshenko. Strength of Material, Part I, Elementary Theory and Problems. 3rd Edition. D. Van Nostrand Co., Inc.. New York, NY. 1955.

The only possibility I see at the moment, due to the fact that you find the results you expect in the /POST1, is that you didn't ask the program to save the results at every timestep of your analysis: with the default setting, it saves only the last substep, so the /POST26 have only one point to...
This feature is only available with Floworks Professional license, not with Standard.
If you bought FW with a Standard lic and you didn't know that, probably your reseller can help you shift the license.
If you use at home a cracked version of FW, ensure that the lic file doesn't contain both...
Piezoelectric materials have the property that they "shrink" when they are subjected to a potential difference, so it makes sense that a displacement response may be expected from a sine voltage.
BUT, as Drej says, you must ensure that:
1) the elements you use have the correct DOFs (not "pure...
Do you want to know a funny thing? In the italian PTC site, this comparison looses any apparent reference to SolidWorks (SW becomes "traditional CAD package"), because in Italy comparative advertising is admitted by law only under very strict conditions, one of which is the complete description...
You can use powders like "Carborundum" on the steel-base contacting surfaces. Dry steel-steel + carborundum raises up the friction factor to 0.5.
Roughening the contacting surfaces can raise it up to 0.25 / 0.3 (but you have to check if there aren't any drawbacks...)
I'd like to know if Workbench 9.0 supports gradiented Boundary Conditions, or more in general, BC that are coordinate-dependent (for example non-uniform pressure distribution, non-uniform temperature distribution, and so on).
Thanks to all!
Ah, OK. This solves the OP question.
But, by the way, are gradiented BC possible in WB9, or not? I never used it until now except for some simple tasks, always used Classical, but as my company is pushing on CAD/FEM interoperation, WB would be great in conjunction with our CAD...
Sie auch muessen Seine Antwort zu erklaeren!!!
(You too have to make your answer clearer)
Refer to what? Must I understand that WB does handle gradiented BC?
Or, simply, did I get confused by reading "...for a thermal analysis, I got..." instead of "...from a thermal analysis, I got..."?
application target = one surface, or one body, or...
The fact is: OK, to have thermal expansion there must be a DELTA-Temperature. But this DELTA can be constant over the, say, surface, or not (=be dependent on the spatial coordinate).
I mean:
If the T is constant over the surface, it will be...
