Help with Reaktoro

[Gregor Reichert]

Hi together,
i fetched actual code from GitHub and compiled the projekt.
With this actual version Reactoro-PP should work without an additional python environment.
I tried this, but DWSIM complains that there is no link to a Python installation folder.

What is going wrong here?
Please help.

[Daniel Medeiros]

Gregor, you don't need the two additional environments that you had to download before, but you need at least one 3.7-3.9 environment for Reaktoro and other DWSIM functionality like PEM Fuel Cell and python (not ironpython) scripting support.

Hi Daniel,
i just installed Python and added the link of the folder into the general settings.

Then i created a new simulation with Reaktoro-PP and Water, NaCl, Na+ and Cl- as components.
I also added a new equilibrium reaction NaCl <-> Na+ + Cl-

A new stream with Water and NaCL was created. Now i get a new error message on calculation:

Location:
Code Location: InitializePythonEnvironment (file 'C:\Users\g90020\source\repos\DWSIM\DWSIM.GlobalSettings\Settings.vb', line 209)

Calling Method: Flash_PT (file 'C:\Users\g90020\source\repos\DWSIM\DWSIM.Thermodynamics.ReaktoroPropertyPackage\ReaktoroFlash.vb', line 120)

This error was raised during the calculation of a Unit Operation or Material Stream.

Hi Gregor, please remind me of this in 7 days (I'm on vacation)

[Gregor Reichert]

Hi Daniel,
I'd like to remember you of that issue as suggested.
I installed Python from the link you suggested within the property package.

p.s.: i defined Python path in general settings:
C:\Users\xxxxxx\Python\WPy64-310111\python-3.10.11.amd64

[Daniel Medeiros]

Hi Gregor. Only Python 3.7 to 3.9 are supported by reaktoro v1.

[Gregor Reichert]

Hi Daniel,
thanks for that information. I will check this out.
Please, could you update the information on your website regarding Reaktoro ?
Do you have a working sample file which might be included to sample files directory to demonstrate usage of that PP?

[Gregor Reichert]

Hi Daniel,
i installed WinPython 3.9 from link you provided on Sourceforge.
I also checked the installation of Python is working via Spyder.

I still get an error on running Reaktoro PP:

Please, could you have a look?

regards, Gregor

Hi Gregor,

I don't know what's going on on your computer. It works for me on a clean DWSIM install and when debugging it as well (Debug/x64).
