What?
Another 2 - 3 days to debug an issue!
This is crazy!
I am attempting to conduct a simple simulation on a part to determing how much deflection the part has under load.
So far it can't be done.
Aluminum Material has been assigned.
Displacement Geometric surfaces has been set.
Force on the geometrical references has been set.
A New Static Analysis Deffinition has been set.
Attempt to run the analysis and I get 3 annoying errors in the diagnostics:
The following materials have invalid Young's Modulus: ALUMINIUM
Cannot perform this operation for this case
Cannot start the design study
If I select ignore, I get ignored...
Blank screen, no available options except to exit the results.
PLEASE DON'T TELL ME IT'S A GRAPHICS CARD THAT NEEDS A DRIVER UPDATE!!
It's the software... Graphics card drivers are tossed into the fray of discussions as a fix all.
Reviewing aluminum materials in both materials_database and materials-library subdirectories:
PTC\Creo 2.0\Common Filles\M090\creo_standards\materials_database METAL_ALUMINIUM_6061.mtl contains no mention of young's modulus,
which maybe the root cause of the failed simulation.
The two .mtl files are written completely different.

Do I dare add a statement to include young's modulus like this?

I really don't appreciate files being peppered all over the server and my hard drive.
There is the aluminium.mat in the material directory, I cannot add the missing data to it through the properties dialog box.
The adv-metal-aluminum.dmt is for appearences.
