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 :math:`\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.
