## 1.4. Material Properties

The Materials details view in CFX-Pre is used to create and modify material properties for both pure substances and mixtures. Pure substances can be solids, liquids or gases. Liquids or gases can be used in fluid domains and solids can be used for either conjugate heat transfer models or particle tracking.

Information on how to set up pure substance or mixture properties in CFX-Pre is available in Materials and Reactions in the CFX-Pre User's Guide.
