Preparing Reports to Monitor Convergence

To judge convergence for this natural convection problem, monitor the heat balance in your model, which sums to zero for a converged case.

Prepare a report for the inner wall.
  1. Create a Heat Transfer report (New > Flow / Energy > Heat Transfer).
  2. Rename the new report to Heat Transfer Inner.
  3. Edit the Parts property.
  4. In the Heat Transfer Inner - Parts dialog, select Regions > ConvectionCylinders > Inner Wall.
  5. Click OK.
Prepare a report for the outer wall.
  1. Create another Heat Transfer report.
  2. Rename this report to Heat Transfer Outer.
  3. Edit the Parts property.
  4. In the Heat Transfer Outer - Parts dialog, select Regions > ConvectionCylinders > Outer Wall.
  5. Click OK.
Prepare an expression report that calculates the heat balance using the results of the reports. A corresponding field function is generated for each report, allowing you to use them in an expression.
  1. Create an Expression report.
  2. Rename this report to Heat Balance.
  3. Click (Custom Editor) in the Definition property.
  4. In the Heat Balance - Definition dialog, enter ${HeatTransferOuterReport} + ${HeatTransferInnerReport}.
  5. Click OK.
  6. Right-click the Heat Balance node and select Create Monitor and Plot from Report.
    New monitor and plot nodes are added to the Monitors and Plots nodes respectively.
