Linear Constraints in ABAQUS using *EQUATION
Hello,
I'm joining 1D beam element to 3D solid elements using a transformation between the 6 dofs of the single node of the beam element, u = [u1, ..., u6], and 3n dofs of n nodes of the solid elements, U = [U1, ..., U3n], at the joint face using a linear transformation, S (6X3n), that I've derived from beam theory, which is essentially the continuity condition. Therefore:
u = S*U
