I/O options for MFREQ analysis

IRA_EM_21281

Hi All,

 

Currently I am getting 0 values results for the acceleration, displacement and 3d element stress quantities when I define the following in the I/O section

 

FORMAT H3D     
OUTPUT,H3D,ALL,BYITER
SCREEN OUT         
ACCELERATION(H3D,REAL) = ALL
DISPLACEMENT(H3D,REAL) = ALL
PRETBOLT (OPTI) = YES
STRESS(H3D,REAL,VON) = YES

 

I suspect I am missing some other setting?

Are you looking at the right frequency value?? Maybe it is just set to Frequency = 0;

You should be using transient animation mode for this, and then change frequencies.

 

Usually people also request results in Punch format to plot them in HyperGraph as well.

 

 

FORMAT H3D     
OUTPUT,H3D,ALL,BYITER  >> this is only for Optimization
SCREEN OUT        >> ok, but doesn't relate to FRF specifically. 
ACCELERATION(H3D,REAL) = ALL >> only Real values? Might want to get Both Real and Imag or Mag and Phase
DISPLACEMENT(H3D,REAL) = ALL>> only Real values? Might want to get Both Real and Imag or Mag and Phase 
PRETBOLT (OPTI) = YES >> doesn't relate to FRF
STRESS(H3D,REAL,VON) = YES >> only Real values? Might want to get Both Real and Imag or Mag and Phase
