LS-DYNA Blast Load Simulation
Budget: ₹600 – ₹1,500 INR
I need a complete finite-element study of an NRC concrete slab under an air-blast load carried out in LS-DYNA. I don’t yet have a mesh or material cards, so the first step will be to build a robust slab model from scratch, assign appropriate concrete and reinforcement definitions, and set up the air-blast loading scenario.
My purpose goes beyond the typical integrity or material-behaviour checks, so the post-processing must focus specifically on displacement and pressure histories at critical nodes or surfaces. Please export those results in a form that can be reviewed in LS-PrePost and also as CSV files for further analysis.
Key points the work must cover
• Create and verify the slab model (geometry, mesh density, boundary conditions).
• Define realistic blast parameters and load application method in LS-DYNA (e.g., CONWEP or equivalent air-blast keyword).
• Run the simulation through to completion without numerical instabilities.
• Provide clear plots and raw data of displacement and pressure versus time.
I’ll review the model setup files, DYNA input decks, and the results package before sign-off.
