call refprop from coolprop in scilab on linux #1303

saha84 · 2016-10-30T09:31:06Z

Hello Ibell,

I have a work to do concerning absorption system working with the ammonia/water mixture. Sadly, I can't do this with Coolprop at present. So I decided to use coolprop to call Refprop using this command:

PropsSI('D','T',300,'P',101325,'REFPROP::ammonia[0.697615]&water[0.302385]')

But the results are always "inf".

I have Refprop installed with wine. Also, I installed the librefprop.so as it was instructed at https://github.com/jowr/librefprop.so.

I even tried to call from python but always no result.

Hi @saha84 - A couple of things to be aware of:

On linux, in scilab, how are you trying to call CoolProp? Runnable code would be nice. Are you calling the DLL through scilab? Or calling python through scilab?

For linux, you should have compiled a shared library of REFPROP and put the shared library in the folder /opt/refprop, along with the fluids and mixtures folders of REFPROP. I recommend my cmake workflow for compiling the shared library of REFPROP: https://github.com/usnistgov/REFPROP-cmake . The wine part is nice, but scilab won't have the ability to use the REFPROP files for windows unless you installed scilab into the wine environment too

Also, linux is case sensitive, so you should be probably calling into REFPROP like

PropsSI('D','T',300,'P',101325,'REFPROP::AMMONIA[0.697615]&WATER[0.302385]')

On my computer (Mac), I get these results:

Python 2.7.11 |Anaconda 2.3.0 (x86_64)| (default, Jun 15 2016, 16:09:16)

but that's a REFPROP problem, not a CoolProp problem.

hello,

Actually ,I call CoolProp from the shared library libcoolprop.so as discribed here: http://coolprop.sourceforge.net/coolprop/wrappers/Scilab/index.html

As for compiling REFPROP, I tried to use your cmake workflow but I always have those errors:

What version of REFPROP were you trying to compile? It seems rather old.
This workflow is for REFPROP version >= 9.0, which you should be upgraded
to at least since there are many improvements and fixes since previous
versions.

It's REFPROP 9.1.
I'm trying to compile it on Archlinux 64 bits

Edit:
I got the same errors with linux mint 64 bits

ibell · 2016-10-31T16:17:53Z

Well, your sources are certainly not for REFPROP 9.1. Can you please file
an issue here and I will investigate:
https://github.com/usnistgov/REFPROP-cmake/issues . I built on ubuntu with
REFPROP 9.1 without any problem.

Hello,
Returning to the main issue, CoolProp still don't recognize REFPROP even after putting the librefprop.so in /opt/refprop along with fluids and mixture folders.

Good news: It is possible to use REFPROP on your system! However, the library
could not be loaded. Please make sure that REFPROP is available on your system.

Neither found in current location nor found in system PATH.
If you already obtained a copy of REFPROP from http://www.nist.gov/srd/,
add location of REFPROP to the PATH environment variable or your library path.

In case you do not use Windows, have a look at https://github.com/jowr/librefprop.so
to find instructions on how to compile your own version of the REFPROP library.

saha84 · 2016-11-01T07:56:39Z

It's working now, I just followed the instruction here: http://stackoverflow.com/questions/13428910/how-to-set-the-environmental-variable-ld-library-path-in-linux

sudo gedit /etc/ld.so.conf.d/randomLibs.conf

then I added the needed path:

/opt/refprop

Save and run sudo ldconfig to update the system with this libs.

now with python I get:

the first error is because the pressure is in KPa

ibell · 2016-11-02T00:50:13Z

Can I please interest you in updating the docs with your experiences: https://github.com/CoolProp/CoolProp/blob/master/Web/coolprop/REFPROP.rst ?

saha84 · 2016-11-02T21:59:50Z

Ok, but I'm not experienced at all :-), I just follow the instructions and it could exit a better way to update the path

ibell · 2016-11-03T00:11:32Z

In any case, we appreciate people that make use of REFPROP contributing,
and updating docs is an easy way to help. That's a useful link you show.
I didn't know about that before.
