Hi everyone, I’ve been leaning on learning Butterfly and CFD analysis in general using Philip Galvan’s tutorial on Youtube (for a fact, for those who wish to learn Butterfly, I highly recommend: Butterfly CFD | Step by step Installation | Fluid dynamics Inside Rhino Grasshopper3D | Part 00 - YouTube).
Philip created a workflow in which he was able to extract the wind velocitie by running a Python script by the end of the solution, which removed the residual values. (also, is it a reliable workflow? just a doubt of mine)
Hence, I’m running some analysis on 3 different timesteps of an urban canyon in my city. I modelled the canyons morphology for the years of 1940, 1980 and 2020, and I was able to run the analysis with no errors on the 1940 and 1980’s morphology. However, on 2020’s morphology (which is relatively taller and denser), the Snappyhex Mesh does not complete the meshing proccess. The meshing error occurs according to the angle I’m rotating the geometry to obtain the wind patterns according to the wind direction extracted from the epw file (respectively running on 295,317 and 331 degrees)
I’ve tried to increase the wind tunnel’s dimensions, lower the cell size, increased the max_global_cells and the glob_refinement_level and still, the meshing process does not finish properly.
Any hints on how to make it work properly?
Here are the files I’m using, I uploaded it on Drive because it is too large to upload it here on the forum.
And also, I’d like to thank you all for all the help throughout my master’s degree, looking forward to contributing to Ladybug’s team with my research.
Warm regards everyone! Hope you all have a nice day and week
