Has anybody come up with a formula to solve the ratio you need for a given first layer height and total block height in blockMesh?
Example: Let's say I'm modeling the flow over a thin plate 4m long as a single block. I want my first layer of cells on the plate to be 0.001m in height. Outside of using multiple blocks, can I specify a certain expansion ratio for a given block height that will give me exactly 0.001m in height on the first layer? |

Nevermind. I found a program that does it in the same forum...
