Updating Salome-Meca

Hi

Looking at Salome Meca, I notice that it uses:
Netgen 4.5 VS Netgen 4.9.9
Aster 9.4 VS Aster 10.0.4-2

Also Solome has been updated with a lot of bug fixes.

I'm trying to figure out how to update it, but it looks quite complicated.

Yes, I want it updated for less bugs, please.

For instance, There's a repeatable bug in the meshing dialogue, that if you forget the geometry object, the GUI will pop under the warning under the dialoge.

I find that there are often errors in meshing.



Salome Meca is powerful, but user-hostile, or average for engineering software, but if word processors GUI's were made like engineering programs, armed people would take to the streets, looking for revenge, and we wouldn't want that : ) I do appreciate being ible to try the software in the first place. thank you.

I also do wish the Salome was in GTK+, but that's the way things go. The users want GTK, because the 3:1, the most popular distro Ubuntu is Gnome based, but as my friend reminds me KDE is a better quality widget set.

Compounding the GUI, I've been through a lot of documentation, but very little of it mentions why one is doing what one is doing, giving the user a situational awareness of the suite. I've learned some from the press tutorial, but because the author is doing both sub-meshes and multiple parts, I's not clear to me when what is necessary for multiple parts, and what is necessary for tighter meshes.

For instance, although I have done FEM on single shapes, I have not gotten anything going on two touching objects. Elsewhere in this forum, I'm going to post asking for help on Fe'ing a dovetail, which are two simple separate parts.

I'll post some of the .stp test objects I have been playing with. I can make some more on request.<br /><br />Post edited by: Brenda EM, at: 2009/06/13 08:03

I dont' think Salome GUI is so bad. Look what is appening in the windows-cad world: a lot packages are migrating to Office-2007 gui style (it seems thay are forced by MS to be Vista-certified), and there are a lot of complains by the users to go back to the traditional GUI, with serious intention to cut annual manteinance until the software will go back to the old gui (example: Solid Edge ST version: there are real riots against new gui).
What Salome really misses is a better geometry module. Now it is very difficult to create sketches, and there is (quite) no way to modify a solid after it has been created.

I am that author ! It seems to me you have a little of confusion beetwen the concept of submeshes and groups.
You make submeshes in places where you want to investigate deeply what is happening. You make 3d-groups when you want to simulate assemblies components (each 3d group will be a component of your assembly). You make 2d-gropus to isolate regions where to apply external loads, where to apply mating conditions, etc etc.

For instance, although I have done FEM on single shapes, I have not gotten anything going on two touching objects. Elsewhere in this forum, I'm going to post asking for help on Fe'ing a dovetail, which are two simple separate parts.

If you start from a step file obtained by an assembly modeled in your cad-package, normally Salome is able to recognize it as assembly (it calls them &quot;compounds&quot;).
The problem that you see is related to the wizards: the &quot;linear elasticity&quot; wizard is able to create code-aster cases that are applicable to single bodies only. If you need to simulate assemblies, you need to use the Eficas editor and write the command file by yourself, without the help of the wizard.<br /><br />Post edited by: Alessandro, at: 2009/06/13 14:12

Thanks for the Pres Tutorial.
I'm sorry about the wizard not working on compound objects. I guess I will have to learn the French in Eficas.

I will post the .stp examples I made.
