1.When defining the start and end diameter of TSJ sections it is important to account for the general direction in which the pipeline will run in the model (e.g. does the pipeline start at the vessel or at the seabed). This will ensure that the sections taper the expected way in the analysis.

2.The number of elements along TSJ sections is controlled by the general mesh settings on the Project component. When a TSJ is positioned along a relatively straight section of pipeline then a relatively coarse mesh is sufficient, but when it is within an area of curvature then a finer mesh is warranted. Note that these needs are often satisfied automatically by the default general mesh settings, but nonetheless it is worth keeping them in mind when building models containing TSJs.
