# 2D Meshing Hypotheses

- Max Element Area

- Length from Edges

- Quadrangle Preference

### Max Element Area

Max Element Area hypothesis is applied for meshing of 2D faces composing your geometrical object. Definition of this hypothesis consists of setting the maximum area of meshing elements (depending on the chosen meshing algorithm it can be triangles or quadrangles), which will compose the mesh of these 2D faces.

See Also a sample TUI Script of a Maximum Element Area hypothesis operation.

### Length from Edges hypothesis

Length from edges hypothesis builds 1D mesh segments having a length calculated as an average edge length for a given wire.

See Also a sample TUI Script of a Length from Edges hypothesis operation.

### Quadrangle Preference

This algorithm can be used only together with Quadrangle (Mapping) algorithm. It allows to build quadrangular meshes even if the number of nodes at the opposite edges of a meshed face is not equal, otherwise this mesh will contain some triangular elements.
