About hypotheses

Hypotheses represent boundary conditions which will be taken into account at calculations of meshes or submeshes basing on geometrical objects. These hypotheses allow you to manage the level of detail of the resulting meshes or submeshes: when applying different hypotheses with different parameters you can preset the quantity of meshing elements which will compose your mesh. So, it will be possible to generate a rough or a more refined mesh or submesh.

In MESH there are the following Basic Hypotheses (to introduce them, you operate numerical values):

• 1D Hypotheses (for meshing of edges):

• Arithmetic 1D

• Average Length

• Deflection 1D

• Number of segments

• Start and end length

• 2D Hypothesis (for meshing of faces):

• Max Element Area

• 3D Hypothesis (for meshing of volumes):

• Max Element Volume

There also exist some Additional Hypotheses

• 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

• the algorithm, which will be selected for meshing of this geometrical object (shape)
