Bubblers and Baffles
The construction of bubblers and baffles has been greatly simplified.
With the new workflow, construct a single channel curve to represent the either the bubbler or the baffle. Assign the appropriate property to the curve, Bubbler or Baffle ( Geometry tab > Properties panel > Change).
Upon meshing, the appropriate element is modeled with the correct coolant flow simulated.
You are no longer required to create a curve for the upward path and a second curve for the downward path. Even with the bubbler or baffle being modeled as a single element, the analysis can proceed.
Note: You need to re-mesh beam elements that have been changed to bubbler or baffle so that the correct flow path can be generated.
