RUNNING A SIMULATION FROM SCRATCH

FIRST CHECK THE UMEAN PROFIEL FOR LAMINA FLOW. TO DO THIS

  • PUT restrt = 0 in input.par file.
  • SET the correct formula for dpmean (Mean pressure gradient) for laminar flow in FLOW_FIELD.f90 module
  • Check Reynold Number and retau value.
  • Check Computational Domain and GRIID POINTS and con1 (Non-uniformity parameter in y-direction) value

LAMINAR TO TURBULENCE TRANSITION SIMULATIONS

  • Adjust the value of re and retau for turbulence.
  • SET the correct formula for dpemean for Turbulence
  • Put irandm =1 in input.par
  • Check Number of Time steps(nsteps)
  • Put isavvf=1 in input.par file and repeat the simulations from the restart file until fully developed turbulent flow is achieved.

RUNNING SIMULATION FROM RESTART FILE

  • Adjust RESTRT=1
  • Make sure that name of restart file is the same in input.par as your restat file.
  • Check your Computational Domain, GRID and con1 value is the same as for the restart file.
  • If you are using any interpolated restart file then make sure that CMPNON subroutine is called for the first time to make UMEAN=1.

 

Before running any simluation, make sure that you have read input.par file completely
