4.14.2.1 Newtonian Fluid

The material type for a Newtonian fluid is “Newtonian fluid”. The following material parameters must be defined:
<mu> shear viscosity [P t]
<kappa> bulk viscosity [P t]
The viscous shear stress for this material model is Stokes' condition is a constitutive assumption that sets , implying that . This assumption is only valid for some fluids (e.g., monoatomic gas [45]). Users may use or ignore this assumption by selecting an appropriate value for .
Example:
<viscous type="Newtonian fluid">
	<mu>0.001</mu>
	<kappa>0</kappa>
</viscous>
