Increase points in a mesh

Hi

I need to increase the amount for points in the mesh so the distance between the points are shorter.
I know it wont be able to make the mesh smoother/finer. But I need the extra vertex for a cfd simulation.
Can anybody show/tell me how?

Hi @Astrid_Kjærbølling
Use Subdivide for that. If you are looking to smooth the mesh as well, you need to fire up Grashopper (and make sure to have the Weaverbird plugin installed - I can’t remember if it’s installed as default). You can use the attached little GrasshopperPlayer file.

Great thank you. Is there a way to get more control over the way it subdivides? Like when you reduce a mesh you can reduce by polygons or percentage

Sounds like the native quad and tri remeshers might be relevant. There’s alse the native mesh refine component:

Either way, it’d help if you post some examples of the input and output you’re working with/expecting.

I don’t know if it helps, but SubDivide supports sub-object selection, so you can select just the area(s) you want to subdivide using Lasso, SelBrush, SelectionFilterFaces and all the other selection tools and filters. It’s not nummerical, but gives you some control over the amount of poly’s. If you need a more specific solution, I’m sure there’s a way to do it in Grasshopper, but the you need to provide more detail.
