Hi,
I would like to define damping coefficient on PARAM card (G), I commonly place the usual value on the card depending of the product that I am evaluating, for example interior parts I use 3%, so on PARAM card I define on G option 3%:
But on due the next article: Frequency Response Analysis (altair.com) , I was told that it is necessary do multiply this value by 2, in order G can be considered in its full value:
Also notice this description:
Could you please let me know your common practices regarding Uniform damping input on PARAM card (G )?
Thanks in advance!!
