      Under the following conditions, pipe to elbow transitioning will done: 1) A straight pipe289 element is next to a curved pipe289 element 2) The section ID’s of the 2 adjacent elements are the same 3) The tangents of the 2 elements at the shared node are within 1 degree. When a transition region is determined, the algorithm marches out along the straight region and converts 289’s to 290’s until a distance of 2 pipe diameters is exceeded. The curved regions will typically have cross-section deformation. We transition these elements so the cross-section deformation can continue into the adjacent straight region.
