RLOAD
Altair EmployeeHallo I am having following questions
1) I am doing Modal Frequency response simulation
In RLoad load collector there is field called TC (see attached file) which expects input in tabular form i have solver deck
in it the values in table is
X(1)= 0.0 Y(1)= 1.0, X(2)= 5000 , Y(2)= 1.0
what is this C ( Damping?), Is it material dependant? how is this tabular input defined
2) There is SDamping Control Card
I want to know how is the the value of g defined in TABDMP1 table in my case it is 0.02. Is it default? Again is it Material dependent?
Thanks and Regards

Hi Pratik,
TABLEDi define C, In other words TC is the C in the equation.
Assuming you are apply a structural damping then you have to select CRIT as type in TABDAMPi card. Here G is 2*Critical damping.

Hi Prakash Thanks for your reply
I would still like to know what physical quantity does this C represent or how it is tio be modelled.

HI,
C is the dynamic parameter (time or frequency function) (TABLEDi) in the Equation.
