28 Nov What are the definitions of FE/Pipe’s boundary conditions?
There are many types of boundary conditions in FE/Pipe. Below is a list of all boundary conditions.
FIXITY – Fixity will restrain all 6 degrees of freedom, not translation or rotation will be allowed at the specified node selected by the user. There is some radial displacement allowed in this boundary condition. If the user does not want any radial displacement, then RIGID should be used, see definition below.
DISPLACEMENT – The user can specify which displacements are allowed. The figure below shows the only allowed displacement in the FY direction and rotation in the RX axis.
