Prepare initial state for explicit dynamic analysis (central difference).

Computes the diagonal effective mass VEC1 = (1/dt^2 + ray_m/(2*dt)) * mass and the virtual past displacements DISP(:,3) = u(-dt), DISP(:,2) = u(-2*dt) used to start the central-difference scheme. All scheme-specific coefficients are local to this subroutine.
