Underrun Protector Submission

In my challenge submission, I faced issues with SimScale; thus, the model lacks extrusions and has a first-order mesh only. The final design features an extruded "bumper," rectangular extrusions for horizontal and vertical beams, and tubular extrusions for stiffeners. This reduces weight by about 30% without compromising stiffness. Solid model mass is 388.58 lbs, while the extruded-based model weighs 271.37 lbs. The respective model files are included, and it's hosted on SimScale's public link. A disclaimer mentions the crude nature of the model due to time constraints. Load areas P1, P2, and P3 were added as 0.02 mm raised rectangular sections on the bumper plate with chamfers for SimScale compatibility; in reality, these "plates" wouldn't significantly impact performance - Heisenberg strikes again!
