Hello All;
I want to solve a heat conduction problem with time-dependent heat source term in OpenFoam.
I need to obtain the temperature field for final time (Tf=10s), only. Also, there is a time-dependent source term in this problem as follows:
S(t)= a j t; wherein a= 12.5 , j is an integer number.Moreover I’d like to get the results for j={1,2,…,50}. I need only to save the temperature field for final time ( Tf=10s). My questions are presented as follows:
1-Is it possible to be saved the temperature field for all j(one directory for every j) only in a 10.0 directory as final time directory in running process in a Non-stop manner (for example in a loop) (also, I don’t need results for other times)?
2- How can I define time-dependent heat source term according to the above mentioned relation for S(t) by fvOptions in OpenFoam 2.3.1?
Cheers,

Ohh!
Unfortunately, I wrote a simple fvOptions and faced some errors!

FoamFile

   version     2.0;
   format      ascii;
   class       dictionary;
   location    "system";
   object      fvOptions;
}

energySource 
{ 
   type            scalarSemiImplicitSource; 
   active          true; 
   selectionMode   all;
 
s0=1e4;
   scalarSemiImplicitSourceCoeffs 
   { 
       volumeMode      specific; 
       injectionRateSuSp 
       { 
           h           (s0 0); 
       } 
   } 
}

With following strange error!!

--> FOAM FATAL IO ERROR:

How can I define a non-constant scalar or time-dependent for injectionRateSuSp at fvOptions?
I'd be appreciated for any help.
