iterative calculation (input/output in worksheet Iteration)
3. Calculate Output
• Acceleration/Velocity/Displacement - Calculate time history of
acceleration, relative velocity and displacement at the top of selected
sub-layers (input/output in worksheet Acceleration ...)
• Stress/Strain - Calculate stress and strain at the middle of selected sublayers (input/output in worksheets Strain ...)
