Hi,
I want to add energy source term in 2d axisymmetric problem. dimension of energy source term is W/m3. I completely confused how can I convert 200 W heat, to this 2d axisymmetric problem? I 3d I have no problem: |

200 [W]/Volume(['your_cell_zone']) This will calculate the volume of the revolved domain and divide your input accordingly to get your source term in W/m^3.

Please describe it for me with one example.We assume that a tube with radius 2cm and 5cm length. what is energy source term for 2d axisymmetric of this case? 200 W/(VOLUME???) How can I calculate volume? |

2) Select expression for the source and hit the "F(x)" icon 3) Type in "200[W]/" and then add Function>Reduction>Volume 4) Replace <location> with the name of the cell zone you would like to add the energy to. See pictures for further detail and check the Fluent guide on using expressions, as Alexander mentioned.
