Can You Help Me How to use these parameters?
These data are used to analize the model?
Can you give us a little more information on what you mean and what material information you need?
The material files (.mtl) are just text files formatted in a certain way that Creo understands. They contain naming and mass property information relative to a material. The system comes with some preinstalled files. By default, there is no material assigned to a part file.
I don't understand How to complete the requested data:
-> "Durezza" (Hardness): the value? For example: 52 HRC, I have to write 52
-> "Tipo di durezza" (Hardness Type): the unit of measure? Brinel, Vickers, Rockwell
-> "Condizione" (Condition): I don't understand what it means
The last question is how the software used all these parameter
Those fields are optional, not mandatory. I am not aware of how the software uses them but they are not used by any of the core modeling or simulation functionality.
Material name fields and density are the only ones that are used by the core Creo application.
PTC added the other fields back in the Wildfire days and have never done anything with them. I can see if you had a hardness that it would affect the results of a Mechanica analysis, but PTC has not linked all of that data together, that I am aware of.
Just to be clear - all of the fields on the structural and thermal tabs are used by Simulate depending on the type of analysis you are running.
