Dynamic Stiffness in Hypermesh
Altair EmployeeHello together,
Is it possible to determine the dynamic stiffness in Hypermesh?
if so, how is the process?
I have already done a Modal Analysis.
if you need any other information tell me plz.
I would be glad about a feedback

Altair EmployeeHello Sanjay,
both informations didnt solve my Problem.
They say, that must perform a FRF. The dynamic stiffness is defined by Dynamic Force/Dynamic Displacement. What is my Dyn.Force and my Dyn.Displacement? Where can I get this?
Can u say the process for the determination of the values.
Thx.
Altair EmployeeWho can help me plz???
I am looking into this. i will get back to you as soon as possible.
Thankyou
Altair EmployeeThank you Sanjay
Hello,
The best way to calculate Dynamic Stiffness is to do a Frequency Response Analysis.
There is no direct way of getting this value from Optistruct
I am attaching a sample deck for this please have a look at it.
Thankyou
What's your definition of 'dynamic stiffness'?
