3.5. Reading CAMPUS Material Property Files

If you have a file containing material properties from the CAMPUS material database (version 3.0 or later), you can import this material data into Ansys Polymat by clicking the Load a Campus File menu item in the top-level Ansys Polymat menu.

  Load a Campus File

The following properties can be read from the CAMPUS file:

  • density of melt

  • thermal conductivity of melt

  • heat capacity of melt

  • curve(s) of viscosity vs. shear rate at a given temperature

  • viscosity model parameters

Note that all data in a CAMPUS file are in the MKS unit system. See Unit Systems for information about converting to a new unit system.

A sample CAMPUS file is shown below:
