Dear all,
I am trying to solve a transient problem using explicit integration scheme (e.g central difference in time) with a lumpped mass technique solving a wave propagation problem. I am wondering if there is anything that is close to this purpose ? Due to the explicit integration scheme , I don't need to form a stiffness matrix K , so do I still need to use the Equationsystem class ? If I want to still use the Equationsystem class , is there a ExplcitTransient System available ? Bascily what I am gonna do is just : acceleration = F_ext./M_lumpped velocity = v_n+dt*accleration disp = u_n + dt*velocity The solve is just cwiseQuotient (coefficient wise Quotient product) of two vectors .
