Triple Point and Max Inputs in MATLAB using REFPROP 9.0 #482

Closed Andrewj0131 closed 6 months ago

Andrewj0131 commented 2 years ago

Hello,

I am trying to use refpropm.m to find fluid properties using the inputs 'R' and 'M' for triple point and Tmax/Pmax, respectively. However, I received the following error message: MicrosoftTeams-image

I checked the refprop.m file and not only do its instructions say that these inputs should be valid, but I cannot find this error message anywhere in the script. The following is the closest message that I was able to find: Capture Right above this error statement, there seem to be cases that allow for 'R' and 'M' as inputs as well.

This script was originally written and run using REFPROP 10.0 before being forwarded to me, though since my REFPROP 9.0 add-in file includes these inputs, I don't see how there would be a compatibility issue.

Any help would be greatly appreciated!

The refpropm wrapper is deprecated and no longer supported.

Switch your code to use the Python interface
