Any Limits to the NX7 Material Properties List (phys_material.dat)
Any Limits to the NX7 Material Properties List (phys_material.dat)
(OP)
In the process of preping a NX7 phys_material.dat file for some company specific material densities and I would like to draw from the experience at EngTips about:
1) No Spaces is a Given for Name Field - but what about maximum amount of characters? Was hoping to use up to 35 characters, too much?
2) Been able to use periods, commas, dashs, percent signs, slashes, parentheses, and underscores - what about pound, more than, and less than signs?
3) Any specific Siemens weblinks that can be referenced on this? Haven't had a lot of time to deep dive GTAC libraries.

RE: Any Limits to the NX7 Material Properties List (phys_material.dat)
The length of a Material name is limited to 81 characters, so your use of 35 should be OK.
As for the legal character set, the 'recommendation' is to limit these to alpha-numeric characters, underscore and hypen. While other characters will generally not be a problem, there IS an absolute restriction against the use of ", &, ', <, >, as these have special meaning when used in an XML file, which the Material names could eventually end up in when using some of the Simulation (CAE) applications.

RE: Any Limits to the NX7 Material Properties List (phys_material.dat)
Question - The Four Types of Materials (ISO, ORTHO, ANISO, and FLUID) are to have a specific range of numbers - or NX7 reading them linearly - but has enough program logic to decipher if it is getting Youngs_Modulus (for ISO and ORTHO) G_1_1 (for ANISO), or Mass_Density (for FLUID)?
Have to ask - because I need to 'retire' the first 51 in the ISO block - and started numbering at 52 - am I going to have to mix my ISOs and Fluids once my linear count gets to 100?

I see that Quotes, More/Less Than Signs, etc. in the Material Name are now kosher? Also, I can use ALUMINUM, ELASTOMER, etc. as Categories?
{facepalm} Is anything in the opening stanza of the .dat still valid - or was there supposed to be some sort of revision control history coded in (more over the 'The following materials were "retired" in NX2')
As for the White Paper/Webpage... looks like this thread maybe the start of one...
RE: Any Limits to the NX7 Material Properties List (phys_material.dat)
The new file where the material properties are now stored can be found in the same folder, but the name has been changed to 'physicalmateriallibrary.xml', and if you look at it you'll see that in the material name fields, that those few non-recommended characters are never used.
Now as to why GTAC sent you that supposed NX 7.5 material library file, I can't understand since OOTB it's no longer being referenced. And while we are still delivering a copy of the 'phys_material.dat' with NX 7.5, it looks nothing like the one you got a copy of, in fact the actual NX 7.5 file now has a big disclaimer at the top of the file explaining how this .dat file is NO longer the file being used by the system.

I also tried added/creating my materials within NX but it only seems to save it for me and not site.
RE: Any Limits to the NX7 Material Properties List (phys_material.dat)
The best approach is to find a material record in the 'physicalmateriallibrary.xml' file similar to the material which you're adding, such as if you adding a 'plastic', find a similar 'plastic', copy and paste the section of entries covering that material and then simply edit the relevant entries.
Note that if you go this route, it may be better to created a copy of the original .xml file, make your additions/removals there, place this file in a convenient (and safe) location and then go to...
Customer Defaults -> Gateway -> Materials -> Location(s)
...and toggle on the first 'Enable' option and enter the path to the new material file, which will now be available as the 'Site' Standard for your users (you can even enforce this so that this is the only optional material file available).
