• flat plate test case has many options

   

• in this preset case the bash script Allrun.sh is modified

   

• in OpenFOAM the type of simulation is determined by the solver which is used

   

• for example simpleFoam (rhoSimpleFoam = compressible) solves steady-state RANS

   

• pisoFoam solves either RANS or LES

   

• wall treatment is set in parameter wall either wallFunction or lowRe

   

• just play around, change parameters and watch the results (gnu)plotted in .pdf files
