Hello everyone!


I am trying to create a structured mesh using the Transfinite command in Gmsh (image attached). As you may notice, due to the curvature of the upper curve, the vertical lines are not quite vertical (I want them to be perfectly vertical). This is possible if I were able to alter the position of the nodes suitably, which is possible in Gmsh using Points in Surface command. However, this Points in Surface command fails when Transfinite command is used and only works for unstructured meshes in Gmsh. So my question is :


1. How to constraint the lines to be vertical? An easier way perhaps?

2. Is it possible to adjust the nodes when Points in Surface and Transfinite commands are used in conjunction?


p.s: Any other open-source meshing tool that can help me do this?


Regards,
Shuvayan
