Could someone suggest how to convert units when I generate grid using snappy? Like in blockMesh, I can specify a convertToMeters value. I used that in snappyHexMesh dict- it didn't work. I have my geometry in units of feet. I want to get the grid in meters. Thanks

prapanj,

after finishing snappyHexMesh, use the utility
transformPoints -scale '(scaleFactor*x scaleFactor*y scaleFactor*z)'

hi,

the convertToMeters won't work in sHM.

create your Mesh with snappy and copy results to your calculation-case-constant folder as usual.

then use console in that case-folder with the command

transformPoints -scale "(x y z)"

where x, y and z are the multiplication factors in x, y and z direction. since you don't want to stretch the grid, it is x = y = z. what value it is to convert feet to meters ... you have to find out yourself.

remember to have your blockMesh-Grid also in feet for sHM operation. The transformPoints-command transforms the whole mesh only.

Thank you. I appreciate it.
