Defining constraint

Altair Forum User

Hello Group

 

I wanted to know whether its is possible to define output as a constraint in optimisation.

 

I am validating my modell with frequency response test

 

I want to vary values of  Material properties like Emodulus, G modulus so that at certain frequencies Frequency Response Function FRF (velocity) is say (+\- 10 % ) of the FRF calculated by test.

 

eg

 

Vary values of

 

E = 1000 mpa to 2000 mpa

G= 200 mpa to 400 mpa

 

so that

at node 256

 

Frq         frf (test)     frf(simulation)

5hz          0.256         (+/- 0.01) of 0.256

10hz        0.586         (+- 0.01) of 0.586

15 hz       1.457          (+- 0.01) of 1.457 etc

 

Is it possible to define constraint this way

 

a suggestion or example tutorial would be quit helpful

 

Thanks and Regards

There may not be an exact example,

 

Perhaps you need to investigate HyperStudy as the tool for this,
