import a file from solid edge

[stefano.garbin]

Maybe we're messing up. . Salvatore87, what kind of "optimisation" do you have to do? try to be a little more detailed in your description to get more detailed answers. in any case:
1-optimization would not define it as one of the latest trends (sperlo per ansys: it has within it optimization modules for more than 20 years), but I would see it rather as a fundamental aspect of fem design+analysis.
2- we distinguish, even if it is not intuitive, between "topological optimization" (i.e. the one in which the fem software progressively removes elements from the mesh to minimize the volume maintaining a constraint on stress and deformations) and "design optimization" (i.e. where one or more parameters of geometric type, material etc. are varied by algorithms in order to minimize an objective function subject to constraints). I personally use the second.
3- All neutral geometries interchange formats (iges, step, parasolid etc.) do not contain any parameters of any type. there are only points, curves and surfaces defined numerically.
4-You can import your "neutro" model into ansys and then change the geometry in a parametric way (yes, because ansys is the only parametric fem, guided in its execution by its language called apdl - ansys parametric design language)
5- Alternatively, you can directly import solid edge prt files with related parameters provided that you have ansys interconnect module licensed.

I would like to make a clear reference to the parameters of design, i.e. to the geometric ones, so this should already make me think that it is not topological optimization, but design optimization. I hope it was clear this time please excuse me for the inaccuracies! Thank you.

I reread chapter 2.1 of the ansys mechanical apdl guide and realized that I said a fair amount of stupidity about topological optimization. in good substance we impose volume reduction and system tries to maximize stiffness.
apart from this, passing to your question, if you have the direct interface (bidirectional, not read-only) between solid edge and ansys and if in solidedge you put a prefix to the variables you want to "export" (eg ds_nomevariable) then ansys (workbench for sure, the classic I don't know) recognizes the variable.

I don't understand what the direct interface is, can you explain yourself better? cmq the realm of ansys on which work is the classic 11.0 not workbench, besides I tried to import the file.par with read input from but as I suspected I did not charge it.without the direct interface as I could do to parameterize the model on ansys?thanks

 

[stefano.garbin]

I'm afraid the classic interface can't handle the solidedge parameters.
worbench does.
Sorry.

stefano excuse if I insist but it is a problem that I would try to solve, because when I realized the model of the tree to elbows, for the thesis of the triennial, I have learned to use solid edge and I would like to see how to import the model on ansys to optimize it. the fact is that I have also installed ansys workbench but I have never used it, now that I should use it for this purpose, it gives me a problem when booting.I can see the screen!

 

[stefano.garbin]

I have no idea what might have happened when watching this screen. . .

in practice when starting the program remains that screen,and even when installing ansys it worked!

 

[stefano.garbin]

re-install it.
or call technical support and expose the problem.
