1. But

Create a field of type cham_no, map, or cham_elem. You can create a field

• by assigning values to knots or meshes,

• by assembling (and/or combining) pieces of existing fields,

• by evaluating the functions of a field of functions to make it a field of reals,

• by modifying the geometric representation of a field (node passage \(\iff\) Gauss points for example),

• by extracting a field from a SD_RESULTAT data structure (evol_ther, evol_noli, mode_meca,…).

• based on the values contained in a TABLE data structure,

*…

You can also use this command to combine several fields linearly, but you can make more « complicated » combinations: multiplication of fields…

Produces a data structure such as cham_no or map or cham_elem

Note: The command is not re-entering except for operations ASSEet COMB.

In this case, the CHAM_GDest keyword is mandatory.
