 ===== Definition =====
-''Fields'' are codes used to refer to nodal values. These codes must be known to use Metafor, and are divided into two entities, a ''Nature'' and a ''Variant''.
+Nodal fields (such as the displacement, the velocity, the temperature, etc.) are defined thanks to a combination of two "codes": a ''Nature'' and a ''Variant''.
-  field = Field(Nature, Variant)
+  field = Field1D(Nature, Variant)
 Here is a list of some ''Nature'' identifiers :
-^  ''Nature''  ^  meaning ^
