Global output control card

Altair Forum User

Hallo Group

I am doing Frequecy response analysis

 

following image ie Gobal output control card

what does the form field indicate eg real , phase, imagnary, both.

Hi Pratik,

I have attached screenshot of user guide information for form field.Let say if it is set to phase. then after solving it will help you to plot curve between phase angle versus frequency.

 

The important results from frequency response analysis usually include the displacement, velocities and acceleration of grid points as well as the forces and stresses of elements.The computed response are complex numbers defined as magnitude and phase (with respect to applied force) or as real and imaginary components,which are vector components of the response in the real/imaginary plane.These quantities are graphically presented.

Hi Rahul

 

Do you know to get values at (velocity/ Dispalcement) at specific grid point/ nodes with out solving for whole structure for direct frecquency response. I tried using options>set1(set  of  interested point ) at global output request. and also defining the set of point under output block

Hi Pratik,

 

Looks like you are looking at wrong parameters. 

 

Instead, Goto Analysis page>> control cards>> Global output request>> Displacement/velocity to output as you have posted in your first post.

 

output blocks may not help when you are doing a FRA.
