Hi everyone,

I met a problem when using funkySetFields for surface scalar field 'phi'. Basically I want to non-dimensionalise my case through dividing the fields by its reference values. I used the code below for velocity and pressure fields and they worked fine.

funkySetFields -field p -keepPatches -expression 'p/0.030625' -time 63 -condition "mag(vector(pos().x,pos().y,0))<=1.0"

funkySetFields -field U -keepPatches -expression 'U/0.175' -time 63 -condition "mag(vector(pos().x,pos().y,0))<=1.0"

However, when it comes to the surface scalar field 'phi', the error turned up like this:

--> FOAM FATAL ERROR:
 Parser Error for driver FieldValueExpressionDriver at "1.5-11" :"syntax error, unexpected number"
"phi/0.01575"
      ^^^^^^^
------|

Context of the error:


- Driver constructed from scratch
  Evaluating expression "phi/0.01575"


    From function parsingValue
    in file lnInclude/CommonValueExpressionDriverI.H at line 1081.

This is the code I use for phi:

funkySetFields -field phi -expression 'phi/0.01575' -time 63

Why I can't use funkySetFields for phi? Is there anything wrong in my code?

I really appreciate it if someone could give me a hand. Thank you very much.

Kind regards,
Tony
