Computes a scalar variable defined as the log (ln) of the pressure divided by the freestream pressure as a function of density, total energy, velocity, ratio of specific heats, and the freestream values

Args:

source_parts:

Any part(s) or a part number.

density:

A density variable or a value.

total_energy:

A total energy variable.

velocity:

A velocity variable.

ratio:

A ‘ratio of specific heats’ variable or a value.

free_density:

A ‘freestream density’ variable or a value(>=1.0).

free_speed_of_sound:

A ‘freestream speed of sound’ variable or a value(>=1.0).

output_varname:

The name of the newly created variable

Returns:

New ENS_VAR instance or None
