If you have used a hinged support or a user defined support
with constraints in rotation, then the bending moment results are always zero
in the associated mesh node. You can use the “Supports” tables (open, from the
Menu bar, the Report generator > Table tab > Results > Forces >
Supports) to check the support results. If you’re still having doubts regarding
this subject, then please send us (on firstname.lastname@example.org) the model in
discussion and point also where the problem occurs.
