I am looking for an experienced CFD engineer to perform a 3D CFD analysis for an SBR air-control valve replacement system. The proposed arrangement consists of: DN500 to DN300 reducer DN300 iris diaphragm control valve DN300 to DN500 expander Upstream and downstream straight pipe sections Required CFD scope: Develop a complete 3D CFD model of the proposed piping and valve arrangement. Simulate three operating conditions: 9,000, 12,000 and 14,000 Nm³/h per SBR. Analyse relevant valve-opening positions, including minimum operating opening, normal control position and fully open condition. Provide pressure, velocity, temperature and density contours. Calculate pressure losses across the reducer, valve, expander and complete assembly. Identify flow separation, recirculation, turbulence, h...

I need a thorough structural calculation and performance check on a newly designed aluminum profile system, with special focus on the largest 3 m × 3 m configuration before cascading the findings to the smaller variants. The study must cover both static and dynamic load analysis so that I can confirm each profile, connection detail, reinforcement option, and fixing method is truly fit for purpose. Material fatigue is my prime concern, so the calculation package has to explore long-term cyclic effects alongside the usual strength and stiffness checks. If you spot joint failure or deformation risks during the process, flag them, but the fatigue life is the critical pass/fail criterion. Please ground every assumption in recognised codes and clearly document the input data, equations, ...

I have a mature consumer product that sells steadily but doesn’t stand up to real-world abuse as well as it should. My goal is to rethink the mechanical design so the next production run is markedly tougher without driving unit cost through the roof. Here is what I need from you: an industrial mechanical designer with at least 7–8 years on the shop-floor side of things—someone who instinctively balances DFMA principles with practical drafting skills. You will start by reviewing the current CAD set and recent failure data, then propose design changes that extend service life, reinforce high-stress areas, and simplify assembly where possible. Key expectations • Dive into the existing 3D model (SolidWorks, Creo, or comparable) and identify weak points through FEA or...

I need a complete electric-motor design tailored for heavy-duty industrial machinery where sustained, high torque is the overriding requirement. The project covers the full engineering cycle—from concept sketches and electromagnetic calculations right through to detailed 3D CAD models, winding data, thermal analysis and a bill of materials ready for prototyping. Key objectives • Deliver continuous high torque at typical industrial supply voltages • Maintain reliability in harsh, high-duty-cycle environments • Meet common efficiency standards—compactness and energy savings are welcome bonuses, but raw torque matters most Your package should include: 1. Electromagnetic design files (Maxwell, Motor-CAD or equivalent) with clear performance plots 2. Mecha...

I am working through Eleation’s HyperWorks course and have 50 pending assignments that must be wrapped up as quickly as possible. Each task follows the standard Eleation template—import the part, create a clean mesh, apply the given boundary conditions, run the required solver (primarily OptiStruct and Radioss), then export results and brief observations. Because this is purely for my personal up-skilling, accuracy and clear step-by-step files matter more than polished presentation. If you have solid, hands-on experience with Altair HyperMesh, HyperView, OptiStruct and Radioss, you should find the workload straightforward; please highlight that experience in your bid. Deliverables • Fully solved model files for all 50 assignments (native .hm, .fem, solver decks) • S...

My rocket-shaped quadcopter is already quick, but I want to squeeze out every bit of performance by refining its aerodynamics. Your main mission is aerodynamic optimization, with special emphasis on lowering drag, boosting useful lift, and ensuring rock-solid stability as velocity climbs. The job at a glance • Rework the current CAD model in SolidWorks so centre of gravity and centre of pressure sit exactly where high-speed flight demands. • Run detailed CFD studies in ANSYS or a comparable solver to quantify lift-to-drag improvements, pressure distributions and flow separation—then iterate the geometry until targets are met. • Back the new shape with FEA to make sure the lighter, sleeker frame still meets strength margins and survives prop-induced vibration. ...

I am looking for a structural engineer with proven experience in CYPE 3D to assist me with the structural analysis of a 2P single-axis solar tracker for a Mechanical Engineering academic project. Proven experience with CYPE 3D is mandatory. Applicants must have actual experience modeling and analyzing steel structures in CYPE 3D. The project is 100% remote, and I would prefer a Spanish-speaking structural engineer based in Latin America. Experience with solar trackers, photovoltaic support structures, light steel structures, wind loads, and Eurocode 3 would be highly valued. The geometry, photovoltaic modules, structural configuration, and main loads are already defined. I also have a similar structural project that can be used as a methodological reference. I mainly need assistance w...

### Hydrodynamic Modelling Validation Freelancer Required I am looking for an experienced **hydrodynamic/coastal modelling freelancer** to assist with **model calibration and validation** for a marine/coastal modelling project. The freelancer should have strong experience in **MIKE 21**, particularly in model calibration, validation, and statistical analysis. ### Scope of Work * Review the existing hydrodynamic model setup and simulation results. * Compare model outputs with **in-situ/current meter observations**. * Perform calibration and validation of: * **Current Speed (CS)** * **Current Direction (CD)** * **Water Level** * Identify the main causes of discrepancies between modelled and observed data. * Adjust/calibrate appropriate model parameters, boundary conditions, bathym...

I’m working on an ANSYS Fluent project and I’m facing an error while updating/generating the mesh. The model includes a honeycomb structure, and the Mesh cell is showing an “Error updating cell Mesh” message in Fluent. I need someone experienced with ANSYS Fluent Meshing to fix the mesh issue and make sure the model is ready for Fluent analysis. I can share the ANSYS project/files and screenshots of the error.

I have an ultrafast-laser–written waveguide already modelled in RSoft (the .dat structure file is ready), yet every attempt to launch light through it in BeamPROP ends with complete loss of signal. I need an RSoft specialist who can open my file, set up the correct input field and boundary conditions, run the propagation and show where the power is disappearing. Your task will be to: • Configure the launch conditions so the field actually couples into the guide. • Optimise any parameters necessary in geometry or materials to remove the loss of signal (mode mismatch or other distortion could be contributing). • Deliver screenshots, the corrected RSoft project file and a brief note explaining what you changed so I can reproduce the result. When you reply, focus...

I’m ready to commission a complete design-to-production package for a warehouse hydraulic lift dedicated to goods and cargo handling. The unit must safely raise and lower loads in the 1–5 ton range and fit seamlessly into a typical warehouse workflow. What I need from you • Engineering design: Detailed 3-D CAD (SolidWorks or similar), hydraulic circuit diagrams, structural calculations and FEA showing the platform, scissor or ram mechanism, guardrails and locking points. • Manufacturing package: DXF files, machining drawings, welding symbols, full bill of materials with sourced components (cylinders, pump, valves, hoses, power unit). • Compliance & safety: Design must respect common warehouse safety practices and relevant standards (ISO 4413, CE direct...
