Hi, Are there any references to "dynamic condensation"? There is a well-known method, static condensation, that condens a stiffness matrix with respect to a particular set of DOF. The subject interested here is "dymanic condensation", that condens eigenvalue equations. For the following example, / \ / \ / \ | K_aa K_ab | | X_1 |=(lambda) | X_1 | | K_ba K_bb | | X_2 | | X_2 | \ / \ / \ / (Due to different font set, it may be difficult in reading the previous equation. Please re-shape it if necessary) Conden out the subset {X_2}, and get the equation [D_aa]{X_1}=(lambda){X_1}, where {X_1} is a subset of {X} and the (labmda) solved in small equation is also eigenvalue of the original equation. Any references to "dynamic condensation"? Thank you.
