hi,

 

ich want to optimize the  density of the concrete plates in OptiStruct.

 

The Variablen are just only  five type density of Materials (rho1 rho2 rho3 rho4 rho5),

 

constrain: von mies stress sigma: sigma = 0.01*density 

 

objekt: Weightoptimization.

 

 

how can i define the density variablen and constrain in OptiStruct?

 

Best Regards, image/emoticons/default_tongue.png' alt=':P' srcset='/emoticons/tongue@2x.png 2x' width='20' height='20'>

    Hi 9527kun,

     

    I think this should be possible using DEQUATION.

     

    But, could you please let us know whether you want the density as sum of all RHO#s or any other expression?

     

    Using Function response you can either create an equation and use the same as a response or use any of the available functions and refer densities through DTABLE and use the same as a response.
