[snappyHexMesh] Doubts about how larger mesh done with blockMesh affects boundaries in snappyHexMesh

rosario · April 12, 2016, 04:52

Hi guys,

I am a new openFoam user and I m trying to use Snappymesh. I am not sure I got it right but I understood that in the blockmesh I should create a block that is bigger than the object i want to snap. Is it right?

If this is the case, how does openFoam know which are my boundary conditions in the object if they are defined based on the simple block in the blockmesh file?

Thanks for your help,

Rosario

Hi Rosario,

It is right. I suggest to have a look at the motorbike tutorial for example, it will help you to understand how to set up your case.

Hope it helps
