I have two questions about modelling 2D axisymmetric flows in OpenFOAM 4.0 in Linux.

1) I recently learned about the following website which contains a utility to take a mesh and collapse it into a wedge thereby preparing it for an axisymmetric simulation. The header of the website states the valid versions, but stops at v2.0. Does anybody know if this utility works with v4.0?

2) I understand that the aforementioned utility takes a mesh and collapses one side to form a wedge. But that web page, nor that OpenFOAM User Manual Sec 5.3.3 (https://cfd.direct/openfoam/user-gui...25-1830005.3.3) indicate what the starting size of the block should be before collapsing. In other words, using the lid-driven-cavity tutorial from the User Manual, its Z thickness is 0.1m. Collapsing this will produce a wedge of a certain angle. However, if the Z thickness instead started at some other arbitrary number (e.g., 2.0m), the resulting wedge angle will be different after collapsing. So presumably, the wedge angle will have an effect on the simulation, correct? If so, what should the wedge angle be?

Thanks,
