OpenFOAM: SnappyHexMesh - Layers

[@poha-pursuit_of_happiness5684]

Good Job foamDude :) waiting eagerly for the next vedio of snappyHexMesh(advanced options) in order to obtain better layers over the geometry. so that the yplus value stays within the range.

thanks!

[@ratulxy]

Awesome tutorial dude!!

[@jekavorobianinov2445]

Do you know how to obtain uniform distribution of boundary layers (especially at inner corners)?

[@laidmessaoudi5335]

Thank you. Merci.

Tank you, really good Video!
Does soneone know why all my cells are divided into triangles?
In your case its only cells close to refinement...

[@muhammadchoudhry5864]

can you run a tutorial on snappy hex Mesh with relative sizes false; (for layer size). Please!

[@ariminin]

Thanks for the nice tutorial! Is it possible to start the simulation as well? I tried to start the simulation with simpleFoam, but didn't get a result.

where is the next one??

This tutorial is not exactly correct. relativeSizes parameter does not define what set of parameters will define layes (first layer, final layer thickness as well as expansion ratio can be set independently). It defines whethet or not the measures are taken relative to the size of adjacent cell or in absolute values (meters). The second mistake is that the size of the layers are not computed by dividing on the factors, but multiplying with them: the final layer will not be as twice as small as the adjcent cell, but actually two times bigger!
