LS-Dyna Rock Net Impact Simulation

I need a complete LS-Dyna explicit analysis that proves a catching net can stop a 200 kg boulder travelling at 250 km/h. This is the first priority, so the model must capture net geometry, support posts, anchorage and realistic material behaviour (wire rope, mesh, energy absorbers). Once the net solution is validated we will move on to the same file set to quantify blast loads on the adjacent building and recommend hardening or other mitigation steps.

Please work directly in LS-Dyna (no simple linear FEM substitutes) and document every assumption so the study is defensible to regulators. Because timing is critical, I will need iterative results as soon as they stabilise; a short written note with screenshots is fine for each run until the final report is ready.

Deliverables
• .k input deck ready to run in LS-Dyna
• Post-processed results in LS-PrePost (plots, animations)
• A concise engineering memo summarising arrest distance, residual forces on anchors, predicted building response and suggested hardening details

To be considered, show comparable impact or blast projects you have already solved with LS-Dyna so I know you can hit the ground running. The schedule is ASAP, so indicate when you can start and how quickly you can turn around the first pass.
