Usage Pattern

// Create subsea tree
SubseaTree tree = new SubseaTree("Well-1 Tree", wellStream);
tree.setTreeType(SubseaTree.TreeType.HORIZONTAL);
tree.setPressureRating(SubseaTree.PressureRating.PR10000);

// Initialize and run mechanical design
tree.initMechanicalDesign();
SubseaTreeMechanicalDesign design = tree.getMechanicalDesign();
design.readDesignSpecifications();
design.calcDesign();

// Get JSON report
String report = design.toJson();

// Get specific results
double boreWall = design.getBoreWallThickness();
double testPressure = design.getTestPressure();
