% File name = ZLxxx, where xxx = analysis number.
% File type = binary direct access. Record length = 24 bytes (6 REAL*4).
% Dynamic analyses only

% Items 1-3 = H1, H2, V translational velocities.
% Items 4-6 = H1, H2, V translational accelerations.
% Rotational velocities and accelerations are not saved.

% The file contains NTIM+1 sets of NNODS records, where NTIM = no.
% of time steps (set 1 = state at start of analysis) and NNODS = no. of
