Documentation for structure of UNV files

Phenom
Phenom

Hello experts,

short question: Is there a documentation about the structure of an UNV File?

 

I did notice that  "Pre Processing Navigator" and "Post Processing Navigator" are able to handle UNV files. As UNV files are ASCII files I wonder if I could use it for plotting model results or nodal or elemental parameters by use of UNV file format in Post.

 

- But what is the structure of an UNV file?

- Which blocks are necessary for complete description?

- What's the content NX is able to understand?

 

So I look for a documentation about structure of UNV file with that content NX Simcenter is capable to import. Is there such a documentation? I've only found bits and pieces about it.

 

Who can help? - Best wishes, Michael

Hi selecx_ct, thank for your contribution.

That page I did found already, too. (I should have announced it, sorry.)

I'm searching for something in the documentation area of NX Simcenter itself.

 

Questions:

- Can I describe only elemental or nodal results or is it possible to construct a file with material behavior of element?

- Which are the correct DATA BLocks for elemental material description? - It looks like being complex to find the right DATA Blocks are necessary in what order (blocks 17**, ...)

- Is it possible to create or construct artificial results with it's correct individual measurement units? Maybe that's the way to "Plot contour" elemental young's modulus and density.

 

As far, best wishes, Michael

@JimB,

 

that looks like the NX documentation I'm looking for.

 

I tried to export an UNV file from NX NASTRAN, Solver: Structural. But "File => Export => Simulation" only supports DAT file. Is there a trick to export UNV or isn't it possible?

 

What type of Simulation do I have to define to get the UNV file export capability? - I want to have a kind of template hot to define properties and materials. Elements and grid points I found in post processing export of results already.

 

Best wishes, Michael

Create an IDEAS UNV solution. Do "Solve, Write Solver Input File" to write out a unv file.

Hi Jim,

Is it correct that I can't define any loads or constraints in this IDEAS UNV solution? Or do I have to use an untouched or maiden-like Sim without other solutions?

Nevertheless, for material description it works in a frighteningly extensive way with complex results. But, the world is complicated, too. - Best wishes, Michael

This is correct. The IDEAS UNV solver language was only intended to be a mechanism to import FE Mesh and properties into NX. There is no actual solver associated to the IDEAS UNV environment, so no need to create boundary conditions. The intent was to allow import of a mesh, then change the solver environment to whatever solver you are actually using and create the boundary conditions there.

@MiDi1791 - It is possible to use UNV Dataset 2414 to plot artifical results, as long as those results are numerical.

 

For artificial results you would generally set Record 9, Field 4 (i.e. Result Type) to 94 (Unknown Scaler). Because your examples (Young's modulus, density) are element related, the Dataset Class (Record 3, Field 1) would probably be 2 (Data on elements).

 

Simcenter also allows for customizing UNV dataset 2414 with specific keywords that will place correct labels for your artifical results in the Post Processing Navigator nodes.

JDunn,

thank you for answering. If I declare an user-defined result type, is there a way to define the measurement unit, too?

Best wishes, Michael
