dear all
I have made a impacting analysis, but after impacting the object is oscillating. how to add damping to the model to remove the oscillating? Thanks!<?xml version="1.0" encoding="UTF-8"?>
Hi,
Can you elaborate bit more?.
If possible, please share the files to my dropbox (input files, out files, .h3d and T01file)

Thanks for your answering. But I can not open your dropbox, I uploaded files there.

This model behavior is dependent on the material characteristics provided and also 2 mm thick. And the boundary conditions also play a role in this,
This is the desired behavior of the model in this loading condition.

hi,
Thanks for your answering!
You mean the oscillating can not be removed by adding damping? If it is possible, how to add damping?
For defining damping in Radioss, you can use /DAMP keyword in engine file. This keyword can be used to define the Rayleigh mass and stiffness damping coefficients applied to a set of nodes.
To know about the input parameters, please refer our help menu.
Please refer this example where damping is applied: http://www.altairuniversity.com/wp-content/uploads/2012/08/Example_16.pdf
