Mesh dense changes significantly

Adjust the gradation rate to a lower value, such as 0.05 or 0.075, and/or constrain the minimum mesh element size according to depth. For syntax guidance on depth-based bounding, refer to the Galveston Bay example.

Hi Keith,

Happy New Year.

I looked at the example but I still could not get the mesh that I am expecting.
I tried:
fh = edgefx('geodata',gdat,'dis',0.3,'fs',3,'max_el_ns',200,'max_el',100,'g',0.1);

This actually violate the value of the grade which is supposed to be between 0.2 and 0.3. The mesh is slightly improved but the transition is still very high.

About nine years ago, I created a mesh using SMS and the transition is very good. I hope I can use OceanMesh2D to get a similar results.

As can be seen from this mesh, the mesh transition location change is quite far from the island. Hence, the transition from coarser mesh to the finer mesh is quite smooth.

I do hope, I can get a similar results using OceanMesh2D as this method is quite convenient to use.

You can change the g parameter to any value you want to achieve any level of mesh smoothness. In the code snippet, you've selected a value of 0.1 for g and saying it should be between 0.2 & 0.3? Please explore the values.
