Ok so basically I am trying to write code that can call from a fluid properties subroutine similar to refprop but it is called FLUID. I need to call the subroutine with temperature and pressure, and have it come back with density, compressibility, and etc. It should be able to do this, however I keep coming back with errors and I'm not sure why..
The error that I am getting according to the code description is due to being "out of range in G table."
Main Program:
The subroutine DRYAIR is one of many (theres one for O2,N2,CO2 etc.) But basically it fills G,TT,DD,GG,SAT,C, and M matrices up with coefficients which are used as transport equations in the fluid subroutine:
DRYAIR CODE:
Finally the code for the FLUID subroutine is here:
I'm really not sure why it is not returning me with density when I specify everything correctly, except I am not sure about how the common and implicit commands are affecting the code so it must be something to do with those.. The problem is that the G tables are "out of range"
Any help is greatly appreciated, and if i get it working I will be more than happy to send you a copy of it.
