Hi all,
I am currently working on a fireFoam case based on oppositeBurningPanels with experimental data as input profile such as :


Code:
U 
  burner
      {
          type            fixedValue;
          value           nonuniform List<vector>
                                 300
                                 (Ö);
      }
Code:
T 
  burner
      {
          type            fixedValue;
          value           nonuniform List<vector>
                                 300
                                 (Ö);
      }
Code:
P_rgh
  burner
      {
          type            fixedFluxPressure;
          value           $internalField;
      }
I am having trouble for the case initialization and donít understand where does the mistake come from. Is someone confident with this nonuniform boundary condition ?
Thanks all for the support.

Regards,

Eliot

What is your error?


Anyway, T cannot be initialized as vector. It is a scalar field.

Thanks for the remark @Joachim. This was actually a tipping mistake

The initialization leads to unrealistic pressure in the fluid (i.e. 10e35 Pa).
I solved it changing the 0/ph_rgh boundary conditions, working 0/ files are attached in case someone is interested .
