物理 Jobs

I need a ANSYS Multiphysics model that accurately represents the behaviour of our medium-voltage cable accessories—primarily the connector section, though insights that also help with related insulators or junction boxes are welcome. The study must cover three tightly linked objectives: • Electrical stress-gradient mapping around the insulation interface, • Steady-state and transient thermal profiles, • Overall performance under combined electrical and mechanical load. I will supply the 3-D geometry, material data (conductivity, permittivity, loss factors, thermal coefficients) and operating limits. Your task is to build the physics, mesh, solve, and deliver: - The native COMSOL file with all study steps, - High-resolution plots of electric field, temperature and von...

I have a novel reluctance-motor geometry sketched out and need a quick, standalone feasibility check focused strictly on the magnetic field distribution. Your task is to set up the model in COMSOL Multiphysics, excite it with the parameters I will share (current, air-gap length, rotor/stator materials), and generate clear field-visualization plots of the magnetic flux density (B-field). Scope • Build or import the supplied 2D axisymmetric or 3D CAD—whichever you believe captures the physics without overcomplicating the run time. • Assign material properties, boundary conditions, and appropriate meshing so saturation and fringing are captured realistically. • Sweep at least two operating points (no-load and expected peak current) to see how the flux paths evolv...

I’m putting together a short series of whiteboard-style video tutorials that teach addition and subtraction to elementary students aged 9-11. The goal is to break each concept into clear, engaging steps, use simple line drawings that animate onto the screen as I speak, and insert quick “pause and solve” moments so learners stay involved. Here’s what I need from you: • 3–5 concise whiteboard/explain-type videos (around 3-5 minutes each) that cover basic facts, regrouping, and multi-digit problems. • Scripting and storyboarding that keep the language age-appropriate while still challenging the learners. • Clean voice-over (native-level English), synchronized to the drawings and handwriting-style text. • Production in 1080p MP4, re...

I manage a motorcycle plant in Pakistan and I’m ready to bring in a hands-on expert who can tighten up our quality control for the scooter line. Day to day you will walk the production floor, run mechanical and visual checks, and fine-tune the machinery settings that most affect final fit and finish. Your eye for consistent welds, paint depth, torque specs, and component tolerances should already be second nature from similar two-wheel projects. I’m particularly interested in candidates who can spot recurring defects early, trace them to a root cause, and work side-by-side with technicians to correct tooling or process parameters on the spot. Familiarity with the standard gauges, calipers, and test rigs used in scooter manufacturing will help you slot in quickly. If you have e...

I have a challenging physics assignment in the field of electromagnetism and need a precise, fully worked-out solution. The task centers on core Maxwell-based analysis, so every derivation must be transparent and verifiable. You will receive the problem statement in PDF as soon as we start; from there, I need you to: • Set up the governing equations clearly, stating all assumptions. • Carry out the algebra and calculus without skipping steps, showing logical flow from start to finish. • Present any numerical results with appropriate units and a short interpretation of what they mean physically. A clean, well-commented PDF or neatly formatted notebook (LaTeX, Mathematica, or Jupyter) is ideal for the final hand-off, along with any auxiliary diagrams you create. Acc...

I’m building a new, PC-first sports title that focuses on the thrill of a single athlete pushing their limits. My goal is to match the depth and polish of a “AAA” release while keeping the creativity and agility of an indie project, and I’m looking for a seasoned game developer who can help me turn the core concept into a playable reality. You’ll work with me from the earliest prototype through to a vertical slice, shaping responsive controls, authentic physics, and a clean, modern visual style that runs smoothly on today’s mid-range PCs. Whether you prefer Unity, Unreal Engine, or another comparable toolset, I’m open—as long as you can demonstrate mastery of the engine’s physics, animation pipelines, and performance-profiling features...
