Dear all,

I'm using "FieldConvert" utility (Shell command) multiple times in a python code and it is working well.
Now I want to use NekPy modules instead to decrease running time of "FieldConvert" execution.
But I ran into a problem and I can't solve it.
I will give you a simple example:
In a python code, when I run the following two similar "FiledConvert" shell commands, I expect to get two identical output and I get it correctly:
!FieldConvert -f -m gradient mesh.xml fields.fld output1.fld
!FieldConvert -f -m gradient mesh.xml fields.fld output2.fld

And in NekPy when I run the equivalent codes twice in my .py code:


from NekPy.FieldUtils import *
import sys
field = Field(sys.argv, force_output=True)

InputModule.Create("xml", field, "mesh.xml").Run()
InputModule.Create("fld", field, "fields.fld").Run()
ProcessModule.Create("gradient", field).Run()
OutputModule.Create("fld", field, output1).Run()

InputModule.Create("xml", field, "mesh.xml").Run()
InputModule.Create("fld", field, "fields.fld").Run()
ProcessModule.Create("gradient", field).Run()
OutputModule.Create("fld", field, output2).Run()

I get two different outputs, output1.fld and output2.fld
It seems that both "gradient" ProcessModule are used in the second output.
I can't find a way to prevent the first "gradient" module from being used in the second output.
Surely this problem have an easy solution.
I would be grateful if you could help me solve this problem.

Sina.
