In this example a pseudo intrinsic function is created to calculated the Reynolds number.

Reynolds is Reynolds is the Quaestor object, Re the top goal for the calculation to be performed with in the Reynolds instance and Length, Speed and Temp are the input arguments.

Relations should be available to compute Re on the basis of Length, Speed and Temp, as in Re=Speed*Length/Nu and Nu=f(Temp). This form of function definition will present theReynoldstheReynolds() function in the expression editor as if it were a Quaestor intrinsic function like SIN() or SELECT(). Any values or parameter can be used to fill in on the locations of Length, Speedand Temp, as in the following example:

RN75 represents the Reynolds number of the propeller blade section at 0.75R in which:
