Harmonic frequency

Altair Forum User

Hi,

 

I get this error when doing a harmonic analysis: 'CARD frequency is required for this subtype'. But where do I assign it? I chose RLOAD1 as the card image in the load collector panel. In the loadcase tab I set freq. resp (direct) as the type.
There are hardly any tutorials available for harmonic analysis. Maybe an addition can be made to demo examples.

 

Thanks,

Hi Ginobilli,

 

Have you created a FREQi card?

 

Please check the tutorial OS-1300: Direct Frequency Response Analysis of a Flat Plate
