[Getdp] Concatenation of field operators

[Thomas_W]

Dear all,

I try to evaluate the following quantity in the Post-processing part,  
where v is the discretized quantity:
|Grad (|Grad (v)|)|.

I tried variants such as:

PostProcessing {
   { Name The; NameOfFormulation f_v;
     Quantity {
       { Name jj;
         Value{
         Local{ [ {d  {d v}*{d v} } ] ; In All;Jacobian JVol; }
         }
       }
     }
   }
}

or also
Local{ [ {d  {Norm[{v}]} } ] ; In All;Jacobian JVol; }.

All these variants yield an error, namely 'syntax error ({)' in the  
corresponding line. It probably has to do with the fact that only v,  
and not Norm[{v}] is the original discretized quantity.

Do you have a solution how to evaluate such a function with GetDP?

Thank you,
Thomas
