multiplicate all elements of volScalarField with scalar to get new volScalarField

maybee · February 17, 2014, 06:27

hi,

I want to do something like this:

Code:

volScalarField TWO = volScalarField ONE * dimensionedScalar SCALAR;

Each element of "volScalarField ONE" should be multiplicated with the "dimensionedScalar SCALAR" -> the result should be "volScalarField TWO". Is this multiplication-operation already defined? How can I do so?

greetings

I am 99% sure this multiplication is already implemented. All you have to do is declare ONE and SCALAR with proper values/declarations prior to declaring TWO like you did there. Then its as simple as:

//ONE and SCALAR declarations
volScalarField TWO = ONE * SCALAR;

Sometimes the best way to figure things out is to simply try it and see what the results are!

hi,

thx for the help

. I know it is good to just try things out, but in this case I am implementing a new algorithm into the multiphaseEulerFoam solver and there are a few "construction sites" now - so I can t test it so easy within the solver - though it is right that I could check if the compiler gives me some error messages for specific code segments
