I am using the following command to do so: *DMAT, MatKD, D,IMPORT, FULL, file.full, STIFF. *PRINT,MatKD, … Webis returned to the global stiffness matrix Kso that the matrix Kcontains the accumulated data from all elements. The global stiffness matrix Kin (P.4) is singular because there is a rigid body motion in the system. In order to remove the rigid body motion, the boundary condition must be applied. The displacement boundary condition is specified by
WebThe element stiffness matrix is zero for most values of iand j, for which the corresponding basis functions are zero within Tk. The full stiffness matrix Ais the sum of the element stiffness matrices. In particular, for basis functions that are only supported locally, the stiffness matrix is sparse. WebMay 17, 2024 · m = factor applied to mass matrix. c = factor applied to damping matrix. kt = factor applied to tangent stiffness matrix. ki = factor applied to initial stiffness matrix (optional, default=0.0) Assembles A = m*M + c*C + kt*KT + ki*KI. Because you don’t want to perform an actual analysis with this integrator, I removed the functionality to ...
