Meshing Engine

When using the Map -> 2d mesh, is the only thing controlling the size of the elements the node/vertex distribution on the nodestrings?

I'm looking to decrease the density of the mesh in an area, while increasing the density at the outer ring of the area. The nodestring "ring" seems to decrease density near it, but then increase in density inside it again.

If you are using "Paving" (not Scalar Paving Density), then the element sizes are controlled by the vertex spacing on the arcs and any refine points. You're welcome to post your .map file or send it to support@aquaveo.com. We can then take a better look to see what is happening.

Yes, its Paving. I just wanted to check and make sure there were no additional parameters that could be used to change the meshing relaxation between arcs or to the overall mesh. It sounds like adding refine points or additional arcs is the sole way to control the change of mesh density.

Is the inner ring its own polygon? If you make it a polygon, the decreased density resolution should go throughout the entire inside of the ring. The bias setting in the polygon properties of your "outside" polygon can influence this as well.
