How to use damping for a component
Altair EmployeeHello guys,
I think it would be helpful to have a step by step tutorial how to enable damping in Hypermesh.
In the following lines I describe how I was trying to enable damping. ( It doesn't work for me atm)
1.assigned materials and properties to components, create a group of nodes in which the damping should occur
2. -in solver browser create->DAMP->DAMP
-assign values for alpha and beta, assign the grnod_id
-assign the skew_id (what differences will be caused when using the global coordinate system or a local system on the component? )
3.enable ENG_DAMP control card, chose property which needs damping ( do I have to chose the property which was created in solver browser? )
Are these steps enough or do I need to do some more steps to get the right damping?
Thank you

Hi,
The steps looks fine. The damping is applied to the nodes specified in the node group, which is mandatory and you have assigned. If you want the damping in a specific direction you can assign it through the local skew. In engine /DAMP card provide the damping coefficient values.
Please go through the files attached where Rayleigh Damping has been applied.
