[FLASH-USERS] Real parameter 'smallrho' error when running FLASH4.8

[Hansen, Eddie]

Hello,

The code is aborting because it can't find runtime parameter 'smallrho', which you are presumably trying to get/initialize inside Simulation_init.  So you either didn't define if inside a Config, or you meant to use 'smlrho' which already exists in a Config elsewhere in the code.

Dear All,

I am facing an error when running FLASH4 with 'mpirun -np 1 flash4' on my laptop. The error is following :

 WARNING: requested real parameter 'smallrho' not found

 Driver_abort called. See log file for details.
 Error message is ERROR: cannot locate real runtime parameter.
 Calling MPI_Abort() for shutdown in   2 seconds!

--------------------------------------------------------------------------
MPI_ABORT was invoked on rank 0 in communicator MPI_COMM_WORLD
with errorcode 1.

NOTE: invoking MPI_ABORT causes Open MPI to kill all MPI processes.
You may or may not see output from other processes, depending on
exactly when Open MPI kills them.

I set up ccsn1d with ./setup CCSN -auto -1d +spherical -objdir ccsn1d and added eos file LS220_240r_140t_50y_analmu_20120628_SVNr28.h5.
I make some changes on flash.par, simulation_data.F90, simulation_init.F90, simulation_init.F90, EOS_data.F90, eosmodule.F90, EOS_wrapped.F90 and eos_idealGamma.F90 files for each i attach screenshot of them. I also attached the screenshot of my config file.

I will be very grateful if you help me solve this error.

Best regards,
Anock Somadder
