    I already have the full cutting-tool and workpiece assembly modelled in SolidWorks. What I now need is a complete machining simulation run in SimScale (or another explicit FEA package you can justify). The cutter is solid carbide and it engages a nickel-silver workpiece. The end goal is to understand the physical response of the cut, so the simulation must clearly capture: • chip formation as the material shears off, • the stress field that builds up in both tool and workpiece, and • the accompanying temperature distribution throughout the cut. Please bring in reliable material models suitable for high-strain-rate metal cutting, apply appropriate boundary conditions, choose a mesh that balances accuracy with runtime, and document every assumption you make.

    I want a fresh 17-ft skiff drawn up—think “Enterprise 17” from Macuch Craft (link below) built in welded aluminum and optimized for inshore fishing. The hull must run skinny yet stay stable when I’m standing on a raised casting platform. Please shape the lines, structure, and deck layout with these essentials in mind: integrated rod storage and generous, watertight storage compartments. Because I’ll be tweaking the layout later, I need editable solidworks assembly files.

    Hydraulic system I am building a device that is based on controlled resistance in A SWINGING MOTION. The device has a swinging arm, swinging back and forth, like a golf swing, a tennis shot or a baseball hit. I want to create the resistance by moving oil from one side to the other side of a double rod small cylinder, through a controlled size orifice. I tested it and it works well and very smooth. I have already done the mechanical design converting the rotational motion to a linear motion and it’s in production already. We must cater for a right-handed and a left-handed swing. There will be 2 models. The one is totally manual and the other electronically controlled by a proportional flow control valve driven by a PLC operated by a UI.

    Dear Sir/Madam, I am the inventor and assignee of newly granted U.S. Patent US 12,612,951 B1, "Helical Tubular Compression Spring" (filed Sep 28, 2025; granted Apr 28, 2026). This architecture integrates guiding and spring functions into a single compact tube: a non‑circular guide‑rod follows a first helical path while a complementary slider bore follows a second path. A designed pitch‑length mismatch bends the guide elastically to deliver a programmable restoring force — enabling non‑linear force curves via geometry and materials. It excels in constrained recoil systems, high‑cycle actuators, and A&D/automotive mechanisms where conventional wire coils limit fatigue life and packaging. High‑spec spring/actuator segments exceed USD 30B SAM (various market reports). T...

    I have a ready-to-use 3D model and I need a straightforward finite element run carried out in ANSYS Workbench. Once I send over the geometry, you’ll apply reasonable loads, boundary conditions and material properties that we agree on, mesh it, solve, and return both the ANSYS project file and a concise results summary (stress plots, /strains, deformation, key numerical values). No geometry creation is required. The humerus bone is an example but you can put pressure on anything you want u just need to use ansys u can use a bone or anything you already made u can do whatever you want u have all the freedom. But make sure u can put pressure show an example of a bone u have always and where u want the pressure and illn tell u if its fright.

    I need a licensed structural / materials engineer to take one insulated concrete panel design for a residential building and turn it into a fully-validated set of calculations and test results. Scope of calculations • Thermal insulation properties – R-value, U-value, expected energy performance across the full panel thickness. • Structural strength – bending, shear and the axial load case I will supply, with clear safety factors for residential code compliance. • Moisture behaviour can be treated qualitatively; the focus is on heat transfer and strength. Scope of testing • Laboratory-grade thermal conductivity test. • Compression test on a representative core sample. • Full-scale or coupon axial load test to confirm the calculated cap...
