Lattice element
I have a model of a reinforced concrete wall, in which the element Lattice employment. Boundary conditions give fixed support on two of the four nodes and apply a force on one of the other free nodes. Running the Ruaumoko you get a file that indicates that the stiffness matrix is singular. Also, it is seen that nodes do not match the defined nodes Ruaumoko graph showing result.

Have you fixed the rotation degrees of freedom, the lattice element only provides stiffness for the displacement degrees of freedom
