Project Title: LS-DYNA Simulation & LaTeX Report – Gun Tube Pressure (FEA Student Project) * Project Description I already have an LS-DYNA simulation model of a gun tube (bouche à feu) that needs some final adjustments, reruns, and a short report in LaTeX. All basic setup (geometry, materials, boundary conditions) is already done — I just need a freelancer to help complete the analysis and write a short technical report based on provided instructions (PDF/photos attached). This is a student project (TP2 – Calcul bouche à feu), so the budget is limited. I’m mainly looking for accurate, fast, and affordable help — perfect for LS-DYNA students, interns, or simulation engineers who want quick extra work. * Tasks to Complete Simulation updates in LS-DYNA Change and rerun simulations with mesh sizes: 2 mm, 1 mm, 0.5 mm, 0.25 mm Perform mesh influence study (compare computation time, internal energy, and relative error) Check energy conservation (using GLSTAT and ASCII outputs) Evaluate plastic strain and stress–strain curves for internal surface elements Determine tube strength using both Von Mises and Saint-Venant criteria Conduct parametric study by changing wall thickness (3 mm, 5 mm, 7 mm) with applied pressure up to 350 MPa Post-processing Extract plots using excel : Internal energy vs. time Stress–strain curve Plastic strain curve Maximum deformation vs. thickness Provide plots in excel Report writing (LaTeX) Write a short report (5–10 pages) in LaTeX Include: setup description, results, discussion, and conclusions Provide both .tex and PDF files * Technical Details Software: LS-DYNA (explicit) Material: Steel 4140 (MAT_003 – Plastic Kinematic) Parameters: ρ = 7.8334E-6 kg/mm³ E = 200 GPa, ν = 0.29 σᵧ = 0.9 GPa, ETAN = 0.5 GPa Pressure: 300 MPa → 350 MPa (parametric) Duration: 2 ms Geometry: L = 100 mm, D = 12.7 mm, thickness = 5 mm * Deliverables LS-DYNA input decks (.k or .dyn) for all cases Post-processing plots (.png/.csv) LaTeX report (.tex + .pdf) Short summary/explanation of results * Budget * Small student budget – please propose your best low fixed price. This is ideal for engineering students, LS-DYNA learners, or freelancers looking to build portfolio work. * Deadline 5–7 days max (earlier is even better) *Skills Required LS-DYNA / FEA Simulation Mechanical or Structural Engineering LaTeX report writing LS-PrePost or data plotting (Python/Matlab optional)

Hii there, I would be glad to assist with refining your Gun Tube LS-DYNA simulation and preparing a clear, technically sound report. With strong experience in explicit dynamics, erosion models, thermal‑mechanical coupling, material cards, and high‑strain‑rate behavior, I can review your current setup, correct modeling gaps, and enhance accuracy for pressure loading, projectile interaction, and structural response. I will analyze your mesh quality, contact definitions, boundary conditions, time-step control, and material formulations to ensure stability and realistic results. If needed, I can optimize hourglass controls, refine element types, adjust ALE/CESE methods, and recalibrate your load curves for more reliable outputs. Once the simulation is improved, I will create a polished engineering report covering methodology, assumptions, validation notes, result interpretation, and recommendations. My goal is to deliver a clean, corrected model and a professional report suitable for academic, research, or defense‑industry use. I will keep communication clear, provide updates, and make revisions promptly to ensure the final outcome meets expectations. Regards, Sohail Jamil

I am the best fit for this LS-DYNA student project because I work routinely with explicit dynamics, mesh-sensitivity studies, and post-processing of GLSTAT/ASCII outputs. I can update your model, rerun all mesh sizes, verify energy balance, extract plastic strain and stress–strain behaviour, and evaluate tube strength using both Von Mises and Saint-Venant criteria. I also have strong experience preparing concise technical LaTeX reports, so the final document will clearly present setup, mesh influence, results, and conclusions. My workflow is fast, accurate and organized, making it ideal for student-budget projects that still require professional-quality FEA and documentation.

Hello, With over 5 years(worth) of experience in using LS-DYNA and FEA simulation for various engineering projects, I am the ideal candidate to complete your gun tube LS-DYNA simulation and report. From my past projects, most of which involved changing mesh size, conducting a mesh influence study, checking energy conservation, and performing parametric studies, I have garnered deep proficiency in ensuring accurate and efficient results. Additionally, given my knowledge of Von Mises and Saint-Venant criteria, I am well placed to help you evaluate plastic strain and stress-strain curves for internal surface elements as well as determine tube strength. Moreover, my skills in post-processing data using LS-PrePost or other tools like Python or MATLAB will prove invaluable in extracting the necessary plots for analysis. My experience with LaTeX report writing will likewise come into play as I deliver a concise, yet comprehensive report that will not exceed your proposed budget limitation of 10 pages. I throw in the delivery of both .tex files and a read-to-use PDF document too. As an added advantage, I can comfortably accommodate the 5-7 days maximum deadline required by the project. Lastly, though not directly related to your project, my programming experiences in Python will undoubtedly serve as a booster by fostering automation where necessary during data analysis or plot extraction stages. Not only is this set to enhance speedy deli THANKS and CHEERS
