Why People Can Always Tell When AI Wrote Your Text
Young adults are letting ChatGPT draft their texts and hard conversations. Here's why it's obvious and what actually works instead.
Simulation is the process of creating a model of a system, such as a network, environment, or process flow, where variables can be experimented with to gather data and to analyze the outcome. A Simulation Engineer enables their client to research and validate the theoretical predictions with different test scenarios before putting those theories into actual practice. They can provide their clients with highly relevant data gathered from simulation to help make decisions with maximum efficiency in fields such as product design, system optimization, and vehicle engineering.
Simulation is used in almost every industry as it offers flexibility and accuracy in experiments to make sure that the design under consideration is secure and able to accomplish tasks effectively. An expert Simulation Engineer is an invaluable asset when it comes to creating accurate simulations based on theoretical equations - they can make sure these simulations are sufficiently up-to-date and that there is consistency in the data collected by these tests.
Here's some projects that our expert Simulation Engineer made real:
Simulation Engineering is a highly sophisticated process, one that requires an experienced engineer who has both technical knowledge and imaginative thinking.

We are seeking an experienced FEA engineer to perform a nonlinear structural and fatigue analysis of a cartridge holder used within an ultra-high-pressure pump assembly. Operating pressure ranges from approximately 200–500 psi inlet pressure to 87,000 psi (approximately 600 MPa / 6,000 bar) outlet pressure, cycling at approximately 100 cycles per minute. The primary purpose of this project is to determine the stresses, deformation, failure mechanism and expected fatigue life of the cart...

The primary goals of this robot are to ensure safety during transport and to allow for quick access to medicines via open compartments. Key Requirements: - Lidar-based navigation system - Safety of transport as the primary objective - Design should include open compartments for quick access to medicines Ideal Skills and Experience: - Expertise in robotics design, particularly for autonomous mobile robots - Strong knowledge of Lidar navigation systems - Experience in designing for safety in dynamic environments, particularly in healthcare settings - Ability to create user-friendly, efficient access points for delivery systems If you have a background in robo...
I have a straightforward structural analysis question that must be solved in ANSYS during a strict 60-minute window tomorrow, 5 pm–6 pm (my local time, UTC + x). At 5 pm I will send the full problem statement—model geometry, loads and boundary conditions—through chat or email, whichever you prefer. By 6 pm I need the finished Workbench file, a quick screenshot of the key result plot (stress or displacement as required by the prompt), and a brief note explaining the setup so I can reference it later. Because of the tight timing, you should already be comfortable working live in ANSYS Mechanical / Workbench for structural analysis and able to troubleshoot quickly without needing extra clarification. The problem is intentionally simple, so no advanced scripting or user sub-...
I need a working TIA Portal V17 project that lets me test and demonstrate basic control logic on a Siemens S7-1200. The goal is to open the file in my own installation, start PLCSIM (standard or Advanced, whichever you prefer), and watch the logic execute without errors. Scope • Create a clean project with the correct S7-1200 hardware configuration. • Write and comment the fundamental control routines I will specify once we start (start/stop, interlocks, simple timers, fault reset). Keep the code in LAD or FBD so it is easy to follow. • Set up tags and watch tables so I can toggle inputs and observe outputs during simulation. • Provide a brief note inside the project (or as a PDF) explaining how to start the simulation and what to look for. Acceptance I will...
I already have the Inventor model ready and simply need the simulation side taken care of. More details with the right candidate Everything must stay native to Autodesk Inventor so I can continue working with the same files. Turnaround is important; 24 hr delivery
I am building a control solution around a Siemens S7-1200 and need the complete PLC program and matching Siemens HMI screens created in TIA Portal. All logic has to compile error-free, follow Siemens best-practice block structure, use symbolic addressing, and include clear comments so I can maintain it later. Once we start I will share the I/O list, functional description, and network settings; you will return a single TIA Portal project that contains both the PLC and HMI configurations. Deliverables • TIA Portal project file (.ap13 or later) with PLC and HMI fully linked • Export of all program blocks and tag tables • Short PDF explaining program structure, tag mapping, and any special instructions • Video or simulation showing each HMI screen driving the PLC ...
I have a manufacturing assembly line that needs a solid Siemens S7-1500 program so the whole process runs reliably without constant operator tweaks. The PLC will take charge of every step on the line—from feeding parts, through each assembly station, to final transfer—maintaining sequence, interlocks, and safety signals while logging key production data for our MES. You’ll be working in TIA Portal (latest V17 preferred, but I can migrate from V16 if needed). The deliverable I expect is a fully commented PLC project file, tested in the simulator first and then ready for onsite download. If you can include basic WinCC Unified screens for status and fault diagnostics, that’s a plus, but the core focus is the ladder/SCL logic that makes the line cycle smoothly. To acc...

I’ve advanced my concept to the detailed-design phase and now need a seasoned mechanical engineer to turn that work into production-ready documentation. The core task is product design, not system optimisation or thermal analysis, so your focus will be on refining geometry, selecting materials, checking tolerances, and validating performance. My expected hand-off package is clear: • 3D CAD models ready for manufacturing (STEP plus native SolidWorks/Inventor/Creo files) • Fully dimensioned technical drawings that meet ISO or ASME standards, including GD&T call-outs and a concise BOM • Simulation reports that demonstrate structural integrity and functional performance under anticipated loads, delivered as both native FEA files and a short PDF summary I will...
Project objective: We are developing a food dehydrator. Our first priority is achieving uniform airflow across all 21 trays and across the usable area of each tray.
