Edit grid after mesh generation

Dear Everyone,

Is it possible to alter the grid after mesh generation in order to obtain a coarser grid in a 3d model? I used ”triangular” as a finite element mesh generator.

Thank you in advance!

You can alter the grid in the sense of refining, moving nodes and switching edges. You can coarsen the mesh if you have refined it previously. You cannot, however, get coarser than the initial status.

That is unfortunate. But thank you for the reply :)
