Femap Express Analysis Help
Femap Express Analysis Help
(OP)
I'm trying to analyze a weldment with Femap Express. I have two questions:
1. I've been saving the weldment and a parasolid then re-importing it as a single part. Is there a way around this? Perhaps the full version of Femap? Does it let you analyze assemblies? If so, how much does that cost?
2. When I try to analyze the weldment as a single part, I have to use boolean operations to unite all the components but keep getting a zero-manifold thickness failure. Is there a way to make the welds have penetration so I can eliminate this problem?

RE: Femap Express Analysis Help
You will likely have to find the place where you have zero manifold thickness and fix that. Once you have a good body, then it should work.
For your second question, Solid Edge has a new designer oriented FEA application that does do assemblies and weldments:

I also posted my PLM Connection (PLM World) 2009 slides in this blog post:

It's probably best to check your VAR on price. I'm on the development side and they don't always give me the latest information. You can buy it stand alone or as part of the new "Solid Edge Premium" package which includes some other things. That might save you some money too.

I converted a bunch of stuff to synchronous and I'm still fighting with it. Sadly, it would have been quicker to part copy and add interferences to analyze in femap express :(
RE: Femap Express Analysis Help
You can do Traditional parts and Traditional assemblies, and weldments. You just just bring it into a sync assembly. This has the added advantage of separating your FEA data in another file.
Since it was our first release, we couldn't do everything. For example, you need a different type of element for frames. I talked to a number of customers and almost everyone had tet meshing followed by 2D plate meshes (for sheetmetal) as the things we needed to start with.
If you can, make an enhancement request to GTAC if frames are really important to your company. I have a few requests now but more requests in other areas. Customer requests carry more weight and we are looking VERY closely at these as we plan out what we do for ST3, ST4 etc.
We are also "full steam ahead" for ST3.

Right now I'm working with my "converted" assembly and I'm getting the can't-mesh error :(
RE: Femap Express Analysis Help
I brought my trad. assembly into a sync. assembly. Do connectors have an effect on the above error? I can't quite figure out how to use them, and auto always results in no connections found.
RE: Femap Express Analysis Help
The mesh problem you got is almost always because of some super small sliver, spike, tiny edge, etc. They often come from very small rounds where some blending is happening. You can set mesh controls for a finer mesh around these locations.
If you want, you can send me the part and I'll take a look (mark.burhop A T siemens.com)

No, connectors don't matter when it comes to meshing, only the geometry.
RE: Femap Express Analysis Help
We are on Solid Edge version 100.00.06.03 (Also known as Solid Edge ST). I have tried everything mentioned in the thread of your discussion. NOTHING has worked. I even built a square beam and tried to simulate a simple cantilevered beam. It would not even do this stress calculation. I got an error message saying that Femap Express could not calculate the mesh and that I should use Femap?? Ridiculous! Seems like a "Bait and Switch"!
A colleague of mine told me that he has had the same experience. He told me that it worked in version 20 but does not work now. I do not know if this is true.
Unfortunately, our management is too stupid to pay for support so I have no way to get help. Any comments you can make about this would be appreciate. I am mad about the time I have already wasted trying to find a solution to this problem!
RE: Femap Express Analysis Help
Nothing has really changed with Femap Express so if anything doesn't work in a new version that does with an old version its a bug that needs to be fixed.

This message says that there is/was a bug in the Solid Edge/Nastran relationship. Unfortunately, our company, at least at my location has...chosen not to pay for maintenance/support. Thereby, we have not been able to load patches and install them. So... I guess I have to do the work around until our management wises up and pays for support so we can implement the newest repairs to the programs. Hopefully that trick will work for now.
A true example of "penny wise and pound foolish".

Where would we be without sat-nav?

Since you are not on maintenance, you can go to the bottom where it says "NX Nastran Users Not Under Maintenance". It will ask your sold to ID and some other things.
After you get in, look for the Solid Edge Patch for your version.
Good Luck,
