d2Value()

PropertyDataType MaterialPropertyLib::IdealGasLawBinaryMixture::d2Value ( VariableArray const & variable_array, Variable const variable1, Variable const variable2, ParameterLib::SpatialPosition const & pos, double const t, double const dt ) const

overridevirtual

Default implementation: 2nd derivative of any constant property is zero.

This virtual method will compute the second derivative of a property with respect to the given variables pv1 and pv2.

dValue()

PropertyDataType MaterialPropertyLib::IdealGasLawBinaryMixture::dValue ( VariableArray const & variable_array, Variable const variable, ParameterLib::SpatialPosition const & pos, double const t, double const dt ) const

overridevirtual

This virtual method will compute the property derivative value based on the variables that are passed as arguments with the default implementation using empty variables array for the previous time step.

The default implementation of this method only returns the property value derivative without altering it.
