Hi

 

Could you help to understand more details, behind online help, about parameters below?

Do I need specific lincense for these parameters?

 

Thanks.

 

Hi Geraldo, 

 

FASTFR : This option is used to activate "The faster modal solution method" for modal frequency response analysis ! 

 

FFRS : The second means FAST Frequency Response Solver, used if you want to activate the external FASTFRS solver. This solver works well for a large modal frequency response. (You have to install it in advance). 

 

FFRSNCPU : used with FFRS. It's useful if you want to define the number of CPUs to be used by the external solver "FAST Frequency Response Solver". 

 

FFRSLFREQ : It's a threshold (cut-off frequency) used to partition your system into low freq and high freq. 

 

Cheers,

Hi Farouk

 

Do you know any external solver "FAST Frequency Response Solver"?

 

Thanks

Hi Geraldo, 

 

I joined a paper in which we explain some Fast FRS development. 

 

Cheers,
