Hi everyone, hope you are healthy,

I am working on a landscape project, and I want to investigate the influence of green corridors/ water walls on local thermal comfort, and I am a beginner to ENVI-MET and Dragonfly.

but the park I’m working on, is located on a sloped terrain, which makes its ENVI-MET modeling challenging for me as an amateur.

does anyone have a tip on how can I model this area? should I flatten the whole region? are there any simplification methods?

Thank you in advance for your tips and suggestions.

Hi @Nimafo,

You could model the elevation using the “DEM” (try to merge all surfaces in a single mesh using a native component of GH). Whilst the different surface material (pavements, alsphalt and so on) are “soil” objects on World XY plane.

If you have problem I can have a test.

Best,  
Antonello

Hi @Nimafo,

Here is an example file:

P.S. I have updated the component to run the simulation with GH.

@Nimafo Can you please share an Example file as I’m facing some issues in adding Fountain in the script and Visualizing in Grasshopper.

I am currently experiencing the same problem. Can I import my sloped topography into ENVI-met using Grasshopper? I do not need to differentiate the surface materials; I only require the topography curves.
