Using named constants in filters/operations

[ssenesi]

Assume you want to convert an energy flux in mass flux using an XIOS filter :

   <field id="tran"    name="tran"  unit="kg m-2 s-1"> evptr / 2.5008E+6</field>

It would be smarter to use (and re-use) a named constant, such as in :

 <variable_definition>
    <variable id="coeffl"  type="float">2.5008E+6</variable>
  </variable_definition>

    <field_definition id="field_definition" operation="instant" prec="4">
        <field id="tran"    name="tran"  unit="kg m-2 s-1"> evptr / coeffl </field>
    </field_definition>

However, this does not work

Hello Stephane,

Have you tried using $coeffl instead of just coeffl?

Yes, it works
Thanks Remi.
