Beginner's question - Why blocking?
 

Hello, everyone!

I'm a beginner to the ANSYS softwares and I'm studying them to run a group of simulations for my bachelor's thesis. While using the ICEM CFD, I'm curious about its blocking function - why does the geometry need to be blocked first and projected to the curves for meshing? What's the advantage of doing that? Will it generate a mesh more fitting the geometry? But isn't the geometry a better projection of itself?

Any answers are welcome and I'd like to know more about the fundamentals of this meshing strategy.

Thank you!
Anthony

blocking is for structured mesh. you start by one block you split it into more blocks so you can adapt all to your geometry.
