FLUX field file — DEX (.dex)
The DEX format stores a single nodal field for Altair/CEDRAT FLUX (electromagnetic and thermal simulation), the field companion to the FLUX mesh (.pf3), following FEconv.

Reading & writing
python
import meshioplusplus
field = meshioplusplus.read("field.dex") # geometry-less Mesh
meshioplusplus.dex.write("out.dex", field)File structure
A two-line header delimited by #, then one row per point holding the point coordinates (x y z) followed by its NB_COMP field values:
# NAME = PIECE FORMULA = mGradT
NB_REAL = 1 NB_COMP = 3 NB_POINT = 25419 #
16.8621677515026 32.8775510204082 0 -4612.18830812659 31808.9451403159 0
...Data mapping
DEX is read into a geometry-less Mesh (no cells) whose points come from the coordinates and whose point_data[<FORMULA>] holds the values (shape (NB_POINT, NB_COMP), or 1-D when NB_COMP == 1). On write, the first point_data array supplies the values, the piece name defaults to PIECE, and the field name comes from the data key. Fields are at nodes only.
Notes
- Implemented against the FEconv format documentation (FEconv is GPL; no code or data is copied — fixtures are generated by round-trip).
