TYPE PHYS_PROPERTY REAL(double) :: value CHARACTER(10) :: units END TYPE PHYS_PROPERTY
PHYS_PROPERTY derived type is used to read the value
and units of physical properties. Two fields compose it, one for the numerical
value and the other for the unit.
It is used only when a given property can be indicated in more than one unit. Otherwise only the numerical value of the property is used.
In the following example all the variables in the NAMELIST have
PHYS_PROPERTY type and both the value and the unit can be
indicated. In this example although the value of the variable
representing the gas density, is not indicated and the unit is needed to force the
output of density results in cm-3.
