Dear mesh users and gmsh team,
I'm using gmsh to mesh a 3D domain (unstructured tetrahedral). My
simulations require a refinement over a line but I don't know how to obtain
a specific element size, namely, increase the element size from a given
point *P* as follows:
|-----------------|-------------|------------|---------|------- *P*
-------|---------|------------|-------------|-----------------|
*A*/2 *A*/4 *A*/8 *A*/16 *A*/32 *A*/32 *A*/16
*A*/8 *A*/4 *A*/2
where *A *is the characteristic length in the domain. Which is the correct
way to get the desired refinement? I'm not sure if a field attractor is a
good solution, if yes, how setup it?
Best regards
O.
