![]() Currently there is a bit of added work for a user to have to construct 2 line segments to accomplish this and then also have to do some additional algebra to ensure that the grid spacing is relatively smooth where the unconstrained ends of the line segments meet. In terms of actually adding functionality what would be the most useful would be the ability to specify the first element length at both ends of a line segment and the growth rate from each end and have gmsh distribute points along the line segment smoothly to obey these progressions. Of course in an ideal world if you could choose from any of the options for a given geometry would be best, but development time is limited, and these are all algorithmically equivalent to each other and can currently be accomplished with only a few extra lines of code in the. If I am understanding you correctly, you can already accomplish this yourself as a user by calculating the number of nodes you need to specify for a given progression to get a desired first element size.įrom a CFD perspective, what would make the most sense intuitively would be to be able to specify the length of the first element and the growth rate / progression and let gmsh calculate the total number of nodes.
