Mises Maximum in Frequency Analysis

I am designing ultrasonic transducer. While performing frequency analysis, in the field output request I set MisesMax but when the analysis starts it gives me this warning "Output request misesmax is not available for this type of analysis".
I do get mises equivalent but misesmax equivalent does not work.
Where am I missing something?

Thanks
 
Stress, strain and displacement values in frequency analyses are only relative - they are normalized and don’t have any physical sense.
 
Dear FEA Way,

I am performing Harmonic Analysis using Steady State Dynamic, Direct approach. Do the stresses and displacements bear any meaning unlike in the Modal Analysis?
If it does not, then what exactly it tells us differently from Modal Analysis?

Thanks
 
In steady state dynamics analysis stresses are meaningful (physical). What I wrote before applies only to modal (frequency) analysis.
 
Dear FEA Way,

My bad, I did not explain my case explicitly.

Thank you for the input.

Being normal is a gift to some, others put tremendous amount of energy to be normal.
