In MESH there are the following + Basic Hypotheses (to introduce them, you operate numerical values):
+For - meshing of edges:
1D Hypotheses (for meshing of edges):
Arithmetic + 1D
Average + Length
Deflection + 1D
Number + of segments
Start + and end length
For - meshing of faces:
2D + Hypothesis (for meshing of faces): +
For - meshing of volumes:
3D + Hypothesis (for meshing of volumes): +
-
+
There also exist some Additional + Hypotheses
-The choice of a hypothesis depends on:
+Propagation of 1D Hypothesis on opposite edges
Length from edges
Non conform mesh allowed
+
The choice of a hypothesis depends on:
+the geometrical object (shape) which will be meshed
