About Conversion of Material Data
The material data in releases before Pro/ENGINEER Wildfire 3.0 is stored in mmatl.lib files or in files with the .mat extension.
You can convert a mmatl.lib file created in Creo Simulate before Pro/ENGINEER Wildfire 3.0 to .mtl files by clicking > in the Materials dialog box. You can edit existing materials definitions, that is, the .mat files in Creo+. These files are saved to the .mtl format when you save the material definition.
If the following parameters are present in existing material definitions, then Creo+ adds the new material as user-defined parameters.
• SHEAR_MODULUS
• THERM_EXPANSION_REF_TEMPERATURE
• STRUCTURAL_DAMPING_COEFFICIENT
• EMMISIVITY
• STRESS_LIMIT_FOR_TENSION
• STRESS_LIMIT_FOR_COMPRESSION
• STRESS_LIMIT_FOR_SHEAR
• Cost (in Creo Simulate)
Conversion of Material in the Model
Before editing a model that contains a material created in Creo Simulate before Pro/ENGINEER Wildfire 3.0 and if this material is a non-isotropic material or a material with functions, parameters, fatigue properties, or failure criteria, then you must convert material data in the model to the latest format. If you edit such a model or material in Creo+ without converting the material to the latest format, you may lose your data associated with the material.
