+==== Old Metafor Version <= 2422 ====
 Used if ''MDE_NDYT=2''. The mechanical scheme must be quasi-static  (''MDE_NDYN=0'') or alpha genealized (''MDE_NDYN=2''). The thermal scheme is trapezoidal (''MDE_THTY=1'') or generalized midpoint (''MDE_THTY=0''). (see [[doc:user:integration:general:parameters]]).

+The mechanical time integration scheme is either quasi static or alpha generalized family. The default _theta  parameter value is 1.0 ([0,1]).
