Moment

The moment of a force is a measure of its tendency to cause a body to rotate about a specific point or axis. For developing moment, the force must act upon the body in such a manner that the body would begin to twist. The magnitude of the moment of a force acting about a point or axis is directly proportional to the distance of the force from the point or axis.

M = F . d

The unit of moment is newton –meter (N-m). A moment also have sense; a clockwise rotation about the center of moment will be considered as positive moment, while a counter-clockwise rotation about the center of moment will be considered negative.

In ANSYS, this boundary condition distributes a moment “about” (the vector of) an axis across one or more flat or curved faces, or about one or more edge or vertex.

Moment boundary condition classified as a remote boundary condition in ansys.
