  I am trying calculating the total power input of a 2D axisymmetric model, a modeled rectangle with r = 1.25mm, h = 0.125mm, with a energy source of 3e8 W/m3. Is the total power of 0.184W correct? By having 3e8 * the cylindrical volume.

  Hi,
  In 2D we assume the domain is 1 m thick.
  For volume intergration, please find more details in user's guide: 38.8. Volume Integration (ansys.com)

  Thank you

  For 2D Axisysmmetric case you provide the source term as it is for full 3D sector.

  What is the 3D volume here? Is it Pi*R^2*h or Sum*2Pi? What is the sum in the volume integration link? Thanks.

  Your calculation in your first post is correct. You get 0.184 W.
