da iges a parasolid

[cesius79]

Hello to all...I have this problem...the client sent me files in iges format...I have to turn them into parasolid to pass them to the finite elements....I tried to open them with inventor(9) and solid edge(v19) and then to save them with name in the desired format but once then open with hypermesh they turn out to be still surfaces....what can I do?who can help me?
Thank you so much to all! !
p.s. wanting I can also use solidworks and catia.. but I don't know what fish to take!
p.p.s. Sorry if the discussion exists but I couldn't find it!

in what sense do you have difficulties with swx or catia? I was about to propose you a try with spaceclaim, but I think any cad can solve your problem. try also to ask in the cae/fem/cfd section: probably hypermesh is able to get a solid from a closed surface.

normally hypermesh is perfectly in degrees to close surfaces, making the edge merge. try to change the tolerance before importing and then change the tolerance of merge on the edges. I don't have the software underhand and I can't tell you the specific commands, but the guide is done pretty well and it's easy to consult.
You can also make a first shell mesh in hypermesh, close the mesh and then create the solid mesh from the shell mesh.
pass for solidworks to close surfaces instead of doing it in hypermesh could be a long waste of time, substantially useless. hypermesh has powerful tools within it. In case with hypermesh you can't, I recommend that you use a non-parametric cad, like rhinoceros, (always you have it) where you can reconstruct the corrupt surfaces and create a closed polysurface (i.e. a solid).

Hi. .
I know topsolid and I know for certain that these issues do not exist, also because it uses parasolid as a motor
Besides importing iges also has possibility to change it by making it in the limit allowed by the parametric file

It is not that it depends only on the software you use to convert, often problems are at the origin (quality of geometry received from the customer).

However I am very interested in these topsolid applications (I say it immediately for transparency: I speak from the point of view of the competition), both the ability to "repair" and close the geometry for the fem, and the neo-parameterization. Can you tell me some links to demonstration videos?

on this link you will find a demonstration of the 7 version of topsolid, however also the current 6.10 and 6.11 that will be released in mid-June are equipped with the same free shape sitema

I guarantee you and exceptional


from all I know, only topsolid does this

even spaceclaim does it (and I think even if-st and maybe cocreate)... however topsolid made me a great impression, congratulations!

the advantage in topsolid compared to spaceclaim (I do not agree well with the spaceclaim product) is that the parametric reconstruction is inserted in the tree and is manageable also to apply relationships like parametric modelers do or you can simply change the recovered quota to change the shape.
I believe that in spaceclaim if I remember well, I repeat I do not know him well tried only for a short time, all the times I have to use the dragman and I can not apply relationships.

hi, I confirm what you write about relationships (not supported by spaceclaim " alone", but something like that is in integration with ansys). for what concerns the tree instead, in sc there is no classic "sequential" tree, but if I define the dimensional control parameters I have a summary table of these parameters editable with keyboard input:finger:

confirm, also solid edge st can impose relationships between faces (live rules) or quotas (pmi) even on imported models.
