      ​@@luizmendes1625I used Rhino7.
      Can't guarantee that it works but until now it worked in every rhino version even though butterfly CFD development was stopped in 2019.

    Hi Philipp,
    I have followed your tutorial, however the solution is not working, as the Butterrfly_loadprobesvalue components are failing to find the probe folder. It is attempting to find the probe folder folder in "Users\username\butterfly\indoor_airflow\postProcessing\probes , but I can see that this folder "postProcessing" does not exist. I can see there is a probes document in "systems" folder. I also attempted to create a probes folder to a new "postProcessing" folder. Do you have any suggestions?
    Even when I try to use the script from the example files folder, it comes up with the same error message as a red component.
    FYI, I am using Rhino in Admin (the file is in meters), and have BlueCFD 2017 installed too.

      @@PhilippGalvanDesign Hi Philipp, thanks for your quick response! I have tried an example script, and the same load probes components are still red, and cant find this folder. Regarding creating an environment, how exactly would I do that? (I'm still a bit new to CFD, although I've watched many of your other grasshopper tutorials)

      I would start here:
      This includes the environment setup for BlueCFD.

      This is my playlist. The second video is an in depth installation guide.
      You need to follow on the dot. Any mistake here and it won't work.
      If you still struggle then there is a problem with your installation possibly a problem with your system. Does you windows username have any special characters or spaces?
      Key items:
      1) BlueCFD 2017 plus setting up the environment
      2) Installation of Butterfly and possibly unlocking the installed component.
      3) Running Rhino in Admin mode!
      Testing more then one of the example files.

    Hi Phillip, I'm utilizing this test to examine airflow for my architecture project, I'm stuck around 12 minutes in on the loadProbesValue segment:
    I've narrowed the problem down to the fact that my folder for this case "indoorflow" [plugged into the caseFromGeos module] does not have a postProcessing folder that has U values in it [I tried substituting the postprocessing folder from a test file and it worked, albiet there were more U values so more arrow vectors].
    How do I generate this U file for my specific file? Am I missing a program or download? Thank you!

    Can we make walls and openings parametrically ? So we can optimize the position of openings after calculating the flow.

      Yes you can but you need to re run the calculation each time you change the position.

    Hi Phillip,
    I really appreciate your video tutorials.
    But like some of us here I am stuck at LoadProbesValue, the error says failing to load probes from the postProcessing folder.
    I then started trouble-shoot from the beginning,
    1. Follow the steps on the installation video
    2. reinstalled both OpenFOAM 2017-2 and Butterfly
    3. Opened Rhino 7 in Admin mode
    4. Rebuilt the script (after copy-paste failed)
    5. Same issue occurred, failing to load probes
    6. I thought it was my windows 11 issue so I switched to another computer with window 10 and followed all the process again but the same issue occured.
    What should I do next?
