Report Dimensionless Numbers from Fluent

    • Chris1opher

      Dear all,

      I am modeling flow in a tube and I want to use dimensionless numbers to evaluate the system.

      For example I want to use the Schmidt-Number and the Reynolds-Number.

      Is it possible to export them from fluent without defining my own expression?

      I could only find Cell-Reynolds-Number, but this is not what I need.

      Kind regards

      If you can define the Custom Field Function or Expression then yes. However, Fluent doesn't know (directly) the diameter that you're interested in so you'd need to either derive it from an area or add it yourself. 

      Remember Fluent holds all data on each cell: most dimensionless numbers would be required for a set location so you may be better off exporting variables (density, viscosity etc) and working it out manually.
