The Newmark accelerations can be noisy for many problems. The Newmark assumption uses the average acceleration [(a(t) + a(t+dt))/2] in its calculation. Initial conditions and nonlinearities can cause the values at “t” and “t+dt” to oscillate (sometimes wildly). Rather than reporting these accelerations in the output, when AVSMOOTH is 1, we report the averaged value so that a smooth solution is seen.

- Why is damped frequency is lower than undamped frequency with viscous damping but larger with structural damping?
- How can I change the normalization method of the vibration modes from modal analysis?
- Why does the prestress from Static analysis does not add up to the stress in Random Vibration analysis?
- A Shock absorber is represented as spring element with damping constant. Modal analysis is performed using Reduced Damped (QRDAMP) solver. How to perform a Modal super position harmonic or transient analysis further ?
- In the results of a modal analysis, how can I define that a frequency is an output parameter ?
- What does the warning “Diagonal of the mass matrix is missing in file” indicate when using RSTMAC command?
- Can you output the frequency response for a total deformation?
- What is mass moment of inertia in Point Mass used for?
- In a Modal Analysis of Mechanical, why aren’t the Participation Factors Summary under Solution Information displayed?
- If the stress is higher than ultimate strength in Response Spectrum Analysis, does this mean that the component may break or yield?
