FLEX Interface


Solver FLEX
Type of mesh unstructured mesh
Dimension 2D and 3D


The FLEX translator creates an unstructured grid file in the "Flex File" format. The three-dimensional coordinates are written using the keyword :xyz. For a model composed of three-dimensional elements, face-to-node and face-to-cell connectivites are written under the keyword :connectivity_faces. For surface mesh, the face connectivity is defined with the :front_faces keyword format.

Creating the FLEX Input File

The translator writes the FLEX input file using an unstructured mesh file and its corresponding boundary conditions file. To create the FLEX file, "Select solver" → FLEX in the "Output" menu. After clicking "Write input " you can specify the following options for the interface:

Defining boundary conditions for FLEX

The translator generates automatically the boundary groups. For grids generated with the HEXA-Mesher or the TETRA-Mesher, the external surface families are used directly to create the different boundary groups.

Available element types

The type of elements supported by the FLEX translator are:
