local coordinate system
local coordinate system
(OP)
hi everybody,
i would like to define a local coordinate system in abaqus/cae version 6.4 that is able to move with the deformed body. I want to use it for applying boundary conditions on a moving surface, that needs to be plane during the deformation. can anybody help me?
thanks in advance,
michael

See:
ABAQUS/CAE User's Manual ->15.14.7 Defining equation constraints

RE: local coordinate system
(1) create reference point on the face to remain planar
(2) create a cartesian csys located at the reference point and oriented such that axis 3 is normal to the planar face
(3) create kinematic coupling: control point is the reference point from (1), surface is the face to remain planar
(4) create a BC, with the local csys from step (2)as the reference and fix in U3
It's pretty easy to do and very easy to create a macro/plugin to automate.
