[FLASH-USERS] Newbie Question: Adding Variables

[Henry (Trae) Winter]

I am teaching myself to use Flash and need some very basic help.  

I want to add clumps of material to the Sod simulation and watch them evolve as the shock hits them.  Simple.  I define an x and y position, a radius, a density, and a pressure for a clump.

In the flash.par file for the Sod problem I add the following:

   #  Clump parameters. rho and pressure are added to background values.
   sim_cposx=  2.5
   sim_cposy=  2.5
   sim_crad=    0.5
   sim_crho=    2
   sim_cp=        0.0 

In my Config file I add the following:

   PARAMETER sim_cposx REAL  2.5
   PARAMETER sim_cposy  REAL 2.5
   PARAMETER sim_crad  REAL  0.5
   PARAMETER sim_crho  REAL  2
   PARAMETER sim_cp     REAL   0.0

In my Simulation_data.F90 file I add:

   real, save :: sim_cposx, sim_cposy, sim_crad, sim_crho, sim_cp


In the Simulation_init.F90 file I add:

  call RuntimeParameters_get('sim_cposx', sim_cposx)
  call RuntimeParameters_get('sim_cposy', sim_cposy)
  call RuntimeParameters_get('sim_crad', sim_crad)
  call RuntimeParameters_get('sim_crho', sim_crho)
  call RuntimeParameters_get('sim_cp', sim_cp)

In the Simulation_initBlock.F90 I add the last line:

  use Simulation_data, ONLY: sim_posn, sim_xCos, sim_yCos, sim_zCos, &    
     &  sim_rhoLeft,  sim_pLeft, sim_uLeft, sim_rhoRight, sim_pRight, sim_uRight, &
     &  sim_smallX, sim_gamma, sim_smallP, &
     &  sim_cposx, sim_cposy, sim_crad, sim_crho, sim_cp

The code compiles.  When I try to run it I get the following error:

   WARNING: requested real parameter 'sim_crho' not found  

What am I forgetting?

Thanks,
-Trae
