Title: COMSOL Induction Heating Model – Debugging and Result Verification Description: I am working on a COMSOL model related to induction heating and need help checking the results and debugging the simulation. The model includes a copper coil, an aluminum cover, and steel pins. The goal is to analyze whether adding the steel pins significantly affects the magnetic field distribution and the heating behavior of the workpiece. There are two tasks: Task 1 – Result verification Two of the COMSOL models can run successfully, but one model produces an unrealistic result. After adding the steel pins, the temperature difference at the same time step is about 200°C, which seems too large. I would like help checking whether this difference is physically reasonable or caused by...

For the next 15 months I will be producing a steady stream of engineering technical manuals that must meet strict compliance requirements in both English and Arabic. The role is full time, office-based in Surrey, so you will be working side-by-side with our engineers and compliance team to capture every specification, safety note and regulatory reference accurately. Day to day, you will translate new manuals as they are released, update existing revisions, and proofread bilingual layouts before they go to print. Because these documents underpin our regulatory submissions, terminology consistency and absolute fidelity to the source material are essential. Expect plenty of CAD diagrams, part lists and standards tables that have to remain perfectly aligned after translation. Key deliverable...

I’d like you to carry out a complete structural study for a single reinforced beam and show, in one concise package, how it performs under the specified service loads. The goal is to know two things with confidence: • the beam’s ultimate load-carrying capacity • the maximum deflection at mid-span and how it compares with code-permitted limits I will supply span length, cross-section geometry, load combinations and any code I must comply with once we start. If an FEA package such as SAP2000, ANSYS, STAAD, or Robot will speed things up, feel free to use it—just attach the native model alongside clear hand or spreadsheet calculations so I can verify the results independently. Whether the beam ends up being steel, concrete or a composite section depends on t...

I have a component that sees time-varying loads and I need its structural response captured through a full transient dynamic study written entirely in Ansys APDL commands. The geometry is already defined in a neutral CAD file; what I’m missing is a robust APDL input deck that sets up material data, meshing, boundary conditions, the load-time history, solution controls and post-processing so I can replay or tweak it on my side without Workbench. Because this is a structural, dynamic, transient analysis, accuracy in time-step selection, damping definition and result extraction (stress, displacement, reaction forces) is critical. Please use standard APDL best practices—element type justification, mass proportional damping where needed, and output requests that minimise file size ...

Improve gain and bandwidth performance 4. Optimize S11 (return loss) and impedance matching 5. Achieve a broadside radiation pattern (0° direction) at both operating frequencies 6...
My Denon AVR drives a home theater system, and the moment the amplifier powers up the speakers erupt with a rolling, thunder-like rumble. The noise stops only when the unit is switched off. All speaker wires, RCA leads, HDMI runs, and power connections have been double-checked and seated firmly, so loose cabling does not appear to be the culprit. I’m looking for an experienced audio-electronics technician who can come on-site, trace the fault, and advise on the fix—whether that turns out to be a failing power-supply capacitor, a grounding issue, or something deeper on the amplifier’s main board. If parts need ordering, I’m happy to approve them once the underlying cause is confirmed. Please let me know: • Your house-call availability in the next week or ...

I’d also appreciate advice on how to present key findings—energy balances, performance curves, and sensitivity analyses—in a clear, professional format that meets academic standards. Deliverables I’m aiming for: ...
I am developing a lightweight detachable bicycle canopy designed for daily commuting in rainy weather. The goal is to create a compact aerodynamic canopy structure that can be quickly mounted on a bicycle and folded for easy storage. The canopy should be designed as a skeletal structural system (no fabric modeling required). The design must be created in Autodesk Fusion 360 as a parametric assembly with proper joints and mechanical relationships.
I need a complete structural evaluation carried out in ANSYS Workbench for a mechanical component that is already modeled. The task is strictly structural—no thermal or fluid-flow coupling—so please focus on static strength, deformation, and, if you judge it helpful, a brief modal check for natural frequencies. This is a single part, not a building, bridge, or aerospace assembly. You will receive: • the clean STEP file of the component • loading diagrams with magnitudes, directions, and boundary conditions Your job: • import and clean the geometry, create a high-quality mesh, and document your mesh-independence check • apply the supplied loads and constraints, then solve for von Mises stress, principal stresses, displacements, and safety factor ...
I need a complete engineering package for a compact, stainless-steel (SS316) system that transfers two high-pressure gases—oxygen and a second gas—from 4 L, 1 800-2 000 psi supply cylinders into a 5 L storage tank. The small tank will serve purely for storage. Filling must occur in a defined sequence: first oxygen to a set intermediate pressure, then the second gas until the vessel reaches roughly 1 000 psi total. Gas purging is the preferred method for every line before and after each fill so that no pressure or cross-contamination remains prior to disconnecting the storage tank. The layout has to stay very tight—short runs only—and all wetted parts are to be SS316. Control and safety monitoring will be handled through a PLC with an HMI. Plan on integrating: &b...

The task is to convert a set of engineering drawings supplied only as PDFs from Arabic into English while maintaining absolute technical accuracy. All dimensions, call-outs, equations, symbols, notes, captions, footnotes and page numbers must stay exactly where the original designer placed them, so the translated file can be over-laid onto the source without any visual drift. Because these drawings will be referenced against ISO, ASTM and IEC requirements, terminology must follow the same standards. Whenever an expression is ambiguous, add a brief in-text comment so reviewers can see the issue immediately. I will provide a brief sample page for you to test your approach; once approved, the full batch follows. Preferred profile • Engineering degree or equivalent experience read...
