About Model Inputs

The following model inputs (which are scalar or vector-field physical quantities that appear as inputs in, for example, a temperature-dependent material property) can be added to models from the Property Group window (vector fields have three components enclosed by curly braces).

Table 9-1: Model Inputs

Model Input	Name/Variable
Absolute Pressure	pA
Concentration	c
Current Density	J {J1, J2, J3}
Effective Plastic Strain	εpe

Frequency	f
Magnetic Field	H {H1, H2, H3}
Magnetic Flux Density	B {B1, B2, B3}
Number Density	nd

Velocity Field	u {u1, u2, u3}

Selection of Model Inputs is standard in most cases. Extra information is included in the documentation as applicable. To define the absolute pressure for heat transfer, see the settings for the Heat Transfer in Fluids node. To define the absolute pressure for a Fluid Flow interface, see the settings for the Fluid Properties node (described for the Laminar Flow interface). If you have a license for a Non-Isothermal Flow interface, see that documentation for further information.
