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
