ArcHydro script problem

I need some help with archydro scripting. I designed my code to automate archydro process; the script runs without error message, but no result. I tried my all the suggestions on the forum but no luck.  Is it how my code is structured or I am missing some in my code? Here is my code:

import arcpy, sys, string, os, ArcHydroTools
arcpy.env.overwriteOutput = True        
arcpy.env.workspace = "C:/Temp/" #arcpy.GetParameterAsText(0)
class myArcHydro:
    def myInputDESC(inputDEM):
        desc = arcpy.Describe(inputDEM)
        print desc.format
        if desc.format != 'GRID':
            arcpy.ASCIIToRaster_conversion(inputDEM, outputDEM, "FLOAT")

    def projCheck():
        dataSpatRef = arcpy.Describe(inputDEM).spatialReference
        if dataSpatRef.Type != "Projected":
            arcpy.AddError("Error: " + inputDEM + " must have a projected coordinate system")

    def myArcHydroTools(inputDEM, outputSHP, outputDIR):
        # Check out any necessary licenses and toolboxes
         #ArcHydroTools.AssignHydroID(tmpPolyFC, "OVERWRITE_YES")
         for dem in inputDEM:
             # Output Filenames
             Fil = outputDIR + "/fil"
             Fdr = outputDIR + "/fdr"
             Fac = outputDIR + "/fac"
             Str = outputDIR + "/str"
             StrLnk = outputDIR + "/strlnk"
             Cat = outputDIR + "/cat"
             Catchment = outputDIR + "/Catchment"
             DrainageLine = outputDIR + "/DrainageLine"
             AdjointCatchment = outputDIR + "/AdjointCatchment"
             DrainagePoint = outputDIR + "/DrainagePoint"

             # Run processes
                 ArcHydroTools.FillSinks(inputDEM, Fil)
                 ArcHydroTools.FlowDirection(Fil, Fdr)
                 ArcHydroTools.FlowAccumulation(Fdr, Fac)
                 ArcHydroTools.StreamDefinition(Fac, "", Str)
                 ArcHydroTools.StreamSegmentation(Str, Fdr, StrLnk)
                 ArcHydroTools.DrainageLineProcessing(StrLnk, Fdr, DrainageLine)
                 ArcHydroTools.CatchmentGridDelineation(Fdr, StrLnk, Cat)
                 ArcHydroTools.CatchmentPolyProcessing(Cat, Catchment)
                 ArcHydroTools.AdjointCatchment(DrainageLine, Catchment, AdjointCatchment)
                 ArcHydroTools.DrainagePointProcessing(Fac, Cat, Catchment, DrainagePoint)
                   arcpy.AddWarning("ERROR. An error has occurred during processing.")

if __name__ == '__main__':
     inputFile = arcpy.GetParameterAsText(0)
     outputFile = arcpy.GetParameterAsText(1)
     outputDIR = arcpy.GetParameterAsText(2)
     # Call the myArcHydroTools function.

     myArcHydroTools(inputFile, outputFile, outputDIR)
     print "success"

Any adept of ArcHydro out there that can help?
