[Getdp] PostOperation

Thu Mar 15 02:11:32 CET 2007

Dear Patrick:

I thank for the suggestion enormously
the PostProceso works correctly...

I need to make another question...

You have some example with magnetic hysteresis in GetDP?

I understand that exist works with the Preisach model, possibly implemented in GetDP.
I am not expert in GetDP and I need to model a typical hysteresis loop (anyone) for the nucleus of a transformer.
Again I thank for your help...

Best regards....

Christian,

You should now write :

PostOperation Map UsingPost Magnet { 
                        Print[ flux, OnElementsOf Todo, LastTimeStepOnly, File "Flujo"       ];
}

Hi Christophe:

Again I need your help..!

During the process of Resolution (Time Step), I generate PostOperation according to:

Resolution {

                        Operation {
                                   TimeLoopTheta [TimeInit, TimeEnd, TimeDelta, TimeTheta] {
                                               IterativeLoop[NL_NbrMaxIter, NL_Eps, NL_Relax[]] {
                                                           GenerateJac[Sys_Mag]; 
                                                           SolveJac[Sys_Mag];
                                               }
                                   SaveSolution[Sys_Mag];
                                   PostOperation[Map];

}

PostOperation Map UsingPost Magnet {
                        Print[ flux,        OnElementsOf Todo,               File "Flujo"       ];
}

In previous versions (GetDP 1.0.1), for each TimeStep generates the archives

Flujo_1.pos
Flujo_2.pos
Flujo_3.pos
Etc

Nevertheless, with the present versions (GetDP 1.2.1) it generates the error

GetDP   : Operation : SaveSolution[Sys_Mag]
GetDP   : Operation : PostOperation
GetDP   : Info      : Selected PostProcessing 'Magnet'
GetDP   : Info      : Selected Mesh 'D:/Tesis/Motor.msh'
GetDP   : Operation : PostOperation 1/1 
GetDP   :          >> 'D:/Tesis/Flujo'
GetDP   : Error     : Empty solution in DofData 0

Now, for each TimeStep,  it rewrites the archive

Flujo.pos

Because it not writes

GetDP   :          >> 'D:/Tesis/Flujo_X'  for each TimeStep?? (X=1,2,3
)

I must modify the PostOperation to obtain a file different for each TimeStep?

Best Regards..!
