Sound_Spinning
some remarks
first point:
with
POST_RELEVE_T(
ACTION=_F(
...
NOM_CHAM='REAC_NODA',
RESULTANTE=('DX','DY','DZ',),
MOMENT=('DRX','DRY','DRZ',),POINT=(50,50,10,),
OPERATION='EXTRACTION',
),
);
one gets as results the three reaction forces "RESULT_X RESULT_Y RESULT_Z"
and three moments named "MOMENT_X MOMENT_Y MOMENT_Z"
which are the moments of the 3 forces about a point those coordinates are the one of POINT
this is not the sum of the applied moment if any
these 3 moments change if the coordinates change
this is quite well explained in the the doc and my book at chapter 4.14
second point:
in code_aster
a moment around an axis perpendicular to a flat plate is not taken into account
in your example the resulting moment MOMENT_Y displayed looks like the sum of the nodal moments applied to the nodes that are shared by the horizontal flange and vertical part of the plate which are the only one where the rotational moment is taken into account
if one wants to apply such a moment to a plate
either one slightly offset the node from the plane
or one create and additional node and a link like LIAISON_SOLIDE
there are also a few other tricks which i wont describe here
