Indoor Probing

[danielcordwell2-glitch]

Hi there @kastnerp

I am attempting to model airflow around and inside a basic model to study the effectiveness of different window opening types. My main issue arises during the probing stage - it is impossible for me to create probing points inside, as seen below, when there is either a floor or ceiling involved.

Using the mesh with no floor or roof results in quite innaccurate windflows shown below.

Is the process I am trying to achieve possible with the current version of Eddy3D, or is this a common issue? I have taken inspiration from the following tutorial: https://www.youtube.com/watch?v=YT-jyb5eg2k - which seemed to work fine but was made 4 years ago. Any support is greatly appreciated.

p.s. I am using Rhino version 8.15 and Eddy3D version 4.15.6.

Kindest regards,

Daniel Cordwell

Hi Daniel,
As ordinary user of Eddy3d I've noticed similar patterns in probing results when I changed number of probes (Points input) without updating (running) this component

Sometimes I aso change "Name" input here to make sure Probing results fully refresh

Hope it helps

Thank you @ohvovka-code, this typically is the solution! @danielcordwell2-glitch could you please try that and report back?

Thank you @ohvovka-code for the suggestion, that seems to work to fix the secondary issue.

My more fundamental issue (as explained above) is the lack of probing points being created when I have geometry with a roof and/or floor.

The issue can be described more easily in this demonstration, where I have made a hole through my geometry and probing points are being made where the hole is but not in other interior areas.

@kastnerp, is there a way of visualising airflow around AND inside a room that is realiable currently? From the tutorial I shared above it seemed to be possible back in 2021.

Any help is greatly appreciated,

regards,

Daniel Cordwell

Hi, are you using the latest version? We have now brep2grid component, it should be able to create the sensor points everywhere. You just need to connect a brep to it as an input, it might be a horizontal plane and as you would like to have, it could also exceed the size of the room itself.

Wow, @karadagi, I just installed the latest version on my personal laptop (I have been working on a school PC in which I need permission to make any software downloads) and this is perfect thank you!!
