After you have created a mesh or sub-mesh with definite applied meshing algorithms and hypotheses you can edit your mesh by assigning other algorithms and/or hypotheses or unassigning the applied hypotheses and algorithms. The editing proceeds in the same way as Mesh Creation.

You can also change values for the current hypothesis by clicking the "Edit Hypothesis" button.

"Edit Hypothesis" button

Mesh entities generated before using changed hypotheses are automatically removed.

See how the mesh constructed on a geometrical object changes if we apply different meshing parameters to it.

Example of a mesh with Max. Element area 2D hypothesis roughly corresponding to 1D hypotheses on edges

And now the Max Element area is greatly reduced
