I have multiple trees in my Rhino file, and I want to run simulations in Grasshopper. However, having so many trees is making my file too large and slowing things down.
Does anyone know how I can turn these trees into blocks so that the file remains lightweight and the simulation runs more efficiently? I’m looking for a way to reference them properly in Grasshopper while keeping the file size manageable.
Any tips or best practices would be greatly appreciated!
post a sample file ?
a few trees/plants ?
what kind of simulation ?
based on nurbs / mesh data ?
guessing on the little information you provide:
block s will reduce the file-size.
depending on the kind of simulation - mostly blocks will not increase performance.
if the simulation is based on mesh data, you should generate meshes with the least amount of polygons.
tip:
change the the title of your topic.
I am not a native speaker but something similar to:
improve performance - simulation with many plants
as we have data-trees i would avoid “tree”.
kind regards -tom
hi i want it for the direct solar radiation simulation , so that uses breps for the simulation for a sample i have this where i tried to delete as many trees i could cause the file was too big to send here

Hi -
The trees in your Rhino file are already blocks.
Grasshopper in Rhino 8 has components to deal with blocks.
Apart from those general observations, it depends on your specific requirements how you deal with this in Grasshopper. I’m not finding anything that is specific enough in the description of your needs.

When i try to use these for the simulations it doesnt select as breps so i was wondering if i need to convert it?or if there is any other way i can do the simulations without comprising the impact of the tress
Hi -
You’ll need to get help from the authors of that simulation package or from people that use that.
If it isn’t a secret, perhaps you could mention the name of that software?

oh ya im using ladybug for the simulations
In that case, you’ll want to get acquainted with their forum: https://discourse.ladybug.tools

Hi okayy will give that a look thankyou so much
Hi @Naik_Shayna
The only thing I can think of is to mesh your tree/s with a low poly count then join them into one mesh as a large disjoint mesh. I think you can still work with it this way in ladybug using a mesh instead of breps. Don’t know if it will calculate faster in Ladybug but it should display and be a lighter file with a lower poly disjointed joined mesh.

Yes, low poly mesh would work great. Because they are blocks already, doing a block swap, or switch out the geometry within the block should be a fairly quick solution.
Having two definitions of each block on the drive will allow you to swap between the detailed and the low mesh version if needed back and forth.
