The most popular substitute uses dictionaries to map cases to # functions, which requires lots of defs or lambdas. While the approach shown # here may be O(n) for cases, it aims to duplicate C's original 'switch' # functionality and structure with reasonable accuracy. # # This class provides the functionality we want. You only need to look at # this if you want to know how this works. It only needs to be defined # once, no need to muck around with its internals. # class switch(object): def __init__(self, value): self.value = value self.fall = False def __iter__(self): """Return the match method once, then stop""" yield self.match raise StopIteration def match(self, *args): """Indicate whether or not to enter a case suite""" if self.fall or not args: return True elif self.value in args: # changed for v1.5, see below self.fall = True return True else: return False # ------> End of Python code snippet copied from an external source #################################################################### # # The rest of this source code was written by me. # Martin Beaudoin, June 2012 class ConvertMixingPlaneBoundaryToNewSyntax(PyFoamApplication): def __init__(self,args=None): description=""" Change MixingPlane boundary condition parameters """ PyFoamApplication.__init__(self, args=args, description=description, usage="%prog ", interspersed=True, changeVersion=False, nr=1) def addOptions(self): self.parser.add_option("--test", action="store_true", default=False, dest="test", help="Only print the new boundary file") def run(self): fName=self.parser.getArgs()[0] boundary=ParsedParameterFile(path.join(".",fName,"constant","polyMesh","boundary"),debug=False,boundaryDict=True) bnd=boundary.content if type(bnd)!=list: print "Problem with boundary file (not a list)" sys.exit(-1) found=False for index in range(0, len(bnd), 2): indexDefPatch=index+1 oldAssembly="" oldOrientation="" if bnd[indexDefPatch]["type"]=="mixingPlane": if bnd[indexDefPatch].has_key("assembly"): print " Replacing the parameter 'assembly' for patch", bnd[index] oldAssembly=bnd[indexDefPatch]["assembly"] del bnd[indexDefPatch]["assembly"] if bnd[indexDefPatch].has_key("orientation"): print " Replacing the parameter 'orientation' for patch", bnd[index] oldOrientation=bnd[indexDefPatch]["orientation"] del bnd[indexDefPatch]["orientation"] if bnd[indexDefPatch].has_key("ribbonPatch")==False: bnd[indexDefPatch]["ribbonPatch"]={} if bnd[indexDefPatch].has_key("zone")==False: bnd[indexDefPatch]["zone"]=bnd[index] + "Zone" if oldAssembly != "": # Converting "assembly" to ribbonPatch/discretisation for case in switch(oldAssembly): if case('master'): bnd[indexDefPatch]["ribbonPatch"]["discretisation"]="masterPatch" break if case('slave'): bnd[indexDefPatch]["ribbonPatch"]["discretisation"]="slavePatch" break if case('both'): bnd[indexDefPatch]["ribbonPatch"]["discretisation"]="bothPatches" break if case('userdefined'): bnd[indexDefPatch]["ribbonPatch"]["discretisation"]="userDefined" break if case(): # default print "Unsupported assembly type: ", oldAssembly if oldOrientation != "": # Converting "orientation" to ribbonPatch/ribbonPatchSweepAxis and # ribbonPatch/ribbonPatchStackAxis for case in switch(oldOrientation): if case('dirX_spanY'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="X" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Y" break if case('dirX_spanZ'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="X" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Z" break if case('dirY_spanX'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Y" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="X" break if case('dirY_spanZ'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Y" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Z" break if case('dirZ_spanX'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Z" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="X" break if case('dirZ_spanY'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Z" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Y" break if case('dirR_spanTheta'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="R" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Theta" break if case('dirR_spanZ'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="R" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Z" break if case('dirTheta_spanZ'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Theta" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Z" break if case('dirTheta_spanR'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Theta" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="R" break if case('dirZ_spanTheta'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Z" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="Theta" break if case('dirZ_spanR'): bnd[indexDefPatch]["ribbonPatch"]["stackAxis"]="Z" bnd[indexDefPatch]["ribbonPatch"]["sweepAxis"]="R" break if case(): # default print "Unsupported orientation type: ", oldOrientation if self.parser.getOptions().test: print boundary else: boundary.writeFile()
