Análisis de elementos finitos Jobs

I will provide DXF drawings for several serpentine interconnect geometries and need a full non-linear finite element study that zeroes in on their load-bearing capacity. The work starts with layered-shell models to screen all designs, then moves to local 3-D refinement wherever strain or stress peaks appear. Scope of the simulations • Uniaxial tensile loading to global engineering strains of 10 %, 20 % and 30 % relative to the initial end-to-end length. • Additional runs that rotate the load direction so any anisotropy in response is captured. • Large-deformation material and geometrical non-linearities must be included. Key outputs for every geometry • Force-displacement curves and the effective axial stiffness. • Maximum principal strain in materials • von...

I am developing a space-saving cable machine for modern fitness studios and I need a complete mechanical design that turns the concept into production-ready files. The unit must let users perform at least leg curls, and the highest priority on the user side is an effortless adjustable-height mechanism. Above all, I have to be certain the base will remain rock-solid and safe under every condition; stability is the single most critical aspect of the build. Core performance targets • 120 kg adjustable weight-stack resistance driven by a low-friction pulley network. • Structural steel or aluminium frame whose worst-case deflection stays below 2 mm with a global factor of safety of 2.5 or higher. • Optimised pulley diameters, cable routing and bearing selection to keep tra...

I have a petroleum hydro-processing unit that requires a robust reactor model built from the ground up. My immediate priority is model creation rather than plant-wide optimisation, and the focus is strictly on the reactor section handling petroleum-based feedstock. Here is what I need: • A first-principles or data-driven reactor model that captures hydrogen consumption, sulfur/nitrogen removal and catalyst performance under typical HDS/Hydro-cracking conditions. • Calibration against operating data I will provide (feed assays, reactor temperatures, pressures and product qualities). • Well-documented equations or code (Python, MATLAB, gPROMS, Aspen Custom Modeler—whichever you prefer) plus a short validation report comparing predictions with plant data. If you...

I need a qualified stress analyst to run five small-diameter petroleum piping models in Caesar II (or an equivalent program) and demonstrate that they meet ASME B31.4. The welded lines are all 150-lb carbon-steel headers that tie into an API 650 storage tank, and the key outcome is an accurate set of nozzle and shell loads so we can finalise the tank reinforcing pad. Scope of analysis • Build or refine the five provided Caesar models, confirm material and section data, and set up all design temperatures and pressures I will supply. • Apply the seismic acceleration parameters I provide and perform a Response Spectrum Analysis. • Combine those seismic results with temperature and internal pressure cases so the governing load combinations are clearly shown. What I wi...

I have derived the governing equations for a rotating, pre-twisted blade treated as a thin shallow shell and now need a full modal vibration study. The formulation already includes the complete mass matrix, the gyroscopic matrix, and separate stiffness contributions for the structural shell, centrifugal stiffening, rotational softening, and an elastic root represented by spring constants. Thickness varies along the span, so any solution must respect the taper, the twist, and the elastic root support while the tip remains free. Your task is to compute the natural frequencies and mode shapes across a practical range of rotational speeds, capturing the combined influence of centrifugal force, Coriolis coupling, and rotational stiffening. Please work directly from the matrix form I provide, o...

I need a complete ETABS model for a residential high-rise (eight floors and above). All architectural and structural drawings are already prepared, so you will be working from detailed plans rather than guessing the layout. What matters most to me is an accurate 3-D model that reflects the provided column grids, slab thicknesses, wall locations, and load cases. Please set up the full analysis environment—materials, section properties, lateral load combinations, and any required diaphragm assignments—so I can open the file and run checks immediately. Deliverables • ETABS *.edb project file ready for analysis • Brief notes explaining modelling assumptions, load combinations, and any simplifications made If you prefer a particular ETABS version, mention it s...

I need a complete finite-element model of a Warren through truss bridge built in ANSYS (Workbench Mechanical or APDL). The task covers geometry creation, material assignment, boundary conditions and, most importantly, a dynamic study that captures wind and traffic effects. For wind, please implement a realistic fluctuating pressure profile; for traffic, model moving axle loads that travel the bridge length with appropriate speed and spacing. Time-history or transient structural analysis is preferred so that true stress-strain and displacement histories can be extracted. I have only a broad idea of where sensors should sit—mid-span, panel points near supports, and a few along the top chord—so I will rely on your structural-health-monitoring experience to pin down the exact n...

I need a complete CFD study that shows how an air-cooled lithium-ion battery pack behaves under load. Your simulation must cover three linked aspects—heat dissipation, temperature distribution throughout the cells and channels, and the resulting fluid-flow characteristics inside the cooling passages. Air will be the only working fluid, so model its thermo-physical properties accurately across the expected temperature range. Please apply the following boundary conditions exactly as stated: • constant temperature at selected casing surfaces (representing contact with a chilled plate) • constant heat flux from each cell core • adiabatic walls on all remaining faces I am interested in clear, actionable results: temperature contours on every cell, velocity vecto...

Hi I will share the details with the shortlisted candidates. Thanks

Using ANSYS Fluent I want a full CFD model of my flat-plate solar water heater to focus on fluid flow dynamics inside the collector when it is charged with an antifreeze solution. The study must couple solar-radiation heat input with the resulting circulation so we can pinpoint pressure drops, velocity profiles, and temperature distribution throughout the manifold and riser tubes. Geometry and boundary conditions are ready in basic CAD; they simply need cleaning and meshing. Once the mesh quality is validated, set up an unsteady solar load (DO or Solar Load Model) that represents typical peak-sun conditions. Radiation is the main transfer mechanism I wish to quantify, so please activate the appropriate radiation model and material optical properties before solving. Deliverables • AN...

I’m looking for a SolidWorks specialist who can jump straight into designing steel mechanical parts and running structural (FEA) simulations on them. The work is ongoing: some weeks I may need a quick bracket modeled and verified for stress, other weeks a more complex sub-assembly that has to meet specific load targets. Typical flow is: • Receive my hand sketch or STEP outline • Build a clean parametric 3D model in SolidWorks • Run a linear static study to confirm safety factors and identify high-stress regions • Tweak geometry if needed, then send me native SolidWorks files, a PDF drawing, and a concise FEA summary (screenshots + key results) Please indicate in your bid how many hours per week you can commit and show one example where you designed a steel...
