Hyperbolic tangent stretching using BlockMesh
Hello everyone!
I was wondering, is it possible to use hyperbolic tangent stretching with blockMesh? I have been searching for a while, but I haven't found anything other than simpleGrading... Thank you very much! Joachim |

However, I don't really understand what you want to be "hyperbolic tangent", so it may be of no help. |
Thank you Yosmcer.
Basically, I don't want to have a constant cell expansion ratio across the domain. I would like to change the node distribution along the edge... |
So edgeGrading will not do the trick (it alow only to define the grading for all edges).
I know no integrated solutions to do what you want, but add-on solutions exist, with name double grading: http://code.google.com/p/blockmeshdg/ Is this what you are looking for? |
arg, that's not really what I am looking for, but thanks anyway!

Hi Joachim,
The short answer to your question will be "no", but if you compare the code linked above with the standard version of blockMesh, then you should be able to identify, where the grading is implemented. From there on it is "merely" a matter of implementing your own preferred stretching function. Kind regards Niels |
