    - Assign Material properties
      This block of information is for assigning the material properties to each element MATID.This block also enables you to identify different regions of the mesh with a unique name so as to use it for post-processing or mesh adaptation. A single MATERIAL can be assigned to more than one MATID.
    - Fluid Material Properties
      The Fluid material type is a parameter used with the BEGIN MATERIAL data block.
    - Workpiece Material Properties
      The Workpiece material is used to describe the extrudate in metal extrusion. Typically, this material is applied to the components in the mesh that describe the negative volume created by the tool (such as, billet, pockets, feeder cavity, welding chamber, porthole etc.) Inside the user profile, we assign this material even to the boundary faces of the workpiece components. HyperXtrude supports the following constitutive models for metals:
    - Polymer Material Properties
      HyperXtrude supports six different models to describe the constitutive behavior of polymers. The material models available in HyperXtrude are:
    - Solid Material Properties
      The Solid material type is a parameter used with the BEGIN MATERIAL data block. This material must be used when solving conjugate heat transfer problems.
    - Tool Material Properties
      The Tool material type is similar to the Solid material type and is a parameter used with the BEGIN MATERIAL data block. This material must be used when solving conjugate heat transfer problems. For Tool, HyperXtrude allows you to specify the conductivity in the form of diagonal tensor.

Fluid Material Properties

The Fluid material type is a parameter used with the BEGIN MATERIAL data block.

Syntax


Fluid Air	{
	FluidType =	"Newtonian"
	Density =	r
	SpecificHeat =	Cp(T)
	Conductivity =	K(T)
	Viscosity =	m (T) \| ho
	CoeffOfThermalExpansion =	β
	VolumetricHeatSource =	Qvol }

Comments

FluidType denotes the type of fluid and it is "Newtonian". Note that the non-Newtonian materials are classified as Polymer for Polymer Processing and Workpiece for Metal Extrusion. The specific heat, thermal conductivity, and viscosity can be input as functions of temperature.

Fluid Material Properties Data Types

The following table contains descriptions of data types for fluid material properties:


Variable Name	Value Type	Remarks
FluidType	String in quotes	"Newtonian" = Newtonian;
Desnity	Real (Constant)	Density of the fluid
SpecificHeat	Real (Constant/Function of Temp.)	Function can be a TABLE1 or EXPRESSION
Conductivity	Real (Constant/Function of Temp.)	Function can be a TABLE1 or EXPRESSION
Viscoscity	Real (Constant/Function of Temp.)	TABLE1 or EXPRESSION are used only for Newtonian fluid. For non-Newtonian fluids the viscosity is computed using the model specific expressions.
CoeffOfThermalExpansion	Real (Constant)	Thermal Expansion coeff.
VolumetricHeatSource	Real (Constant)	Value per unit volume.
