I tried to create a new field by dividing two fields , suppose "m" and "l". "m" is a volvectorfield and "l" is a volscalarfield.
I want to input this into the solver from "0" folder from fields already available.I haven't run the solver yet as this is a required input.
I Tried using :

  foamPostProcess -func divide -fields '(m l)'

But It is showing error as follows:

 Create time

Create mesh for time = 0



--> FOAM FATAL IO ERROR:
functionObject::fieldsExpression divide requires at least 2 fields only 0 provided: 0()

file: /home/josepaulb/Personal_project/system/functions/divide from line 4 to line 8.

    From function Foam::functionObjects::fieldsExpression::fieldsExpression(const Foam::word&, const Foam::Time&, const Foam::dictionary&, const Foam::wordList&, const Foam::word&)
    in file fieldsExpression/fieldsExpression.C at line 91.

FOAM exiting

I tried different combinations like fields, funcs .But still it shows one error or the other . Can anyone help me in this?
I checked user guide of Openfoam 12 which I am using , but there was no example for divide function.
If any more information is required, I will give them.
