I want a fully documented chemical formula for a very strong, foul-smelling liquid intended for outdoor objects as a nuisance or prank. Once applied it must cling to wood, metal, plastic or stone and keep releasing an unpleasant scent for roughly 30 days. The odor should not wash away with ordinary water, household cleaners or detergents, and even heavy perfume sprays shouldn’t mask it. I also need a companion neutralising solution that removes the smell quickly and completely when applied. Zero toxicity is critical: no skin irritation, no environmental harm, and no restricted or controlled substances. The formulation has to be practical to mix with readily available, legal ingredients and scalable from a small test batch (100 ml) to several litres. Deliverables • Detailed i...

I need a complete, start-to-finish ANSYS Fluent study of turbulent, two-phase boiling and condensation inside a 2-D domain. You will begin by building the geometry from scratch, then create a high-quality mesh that resolves boundary layers and interfacial regions accurately. After that, set up the physics: turbulent flow (k-ω SST or a comparable model), a multiphase formulation suited to boiling/condensation (VOF with phase-change, or a similar approach), and all relevant material properties and thermal boundary conditions. Once the case is running, iterate until residuals and key monitors converge soundly, then post-process temperature fields, volume-fraction contours, velocity vectors, and heat-flux data so the phase-change behaviour is clear. Please include a brief summary of ass...

I need a complete Fusion 360 simulation that pits two sandwich panel designs against each other: one with a hexagonal aluminium core, the other with a square aluminium core. Both panels use the same aluminium faces so the only variable is the internal cell geometry. The simulation must focus exclusively on load-bearing capacity under identical conditions; thermal or vibration behaviour is out of scope for this task. The panels should be restrained with fixed edges to mimic a rigid support frame. I want the study to reveal maximum stress, peak displacement and overall safety factor for each geometry, clearly highlighting which core layout carries the greater load before failure. Please provide the editable Fusion 360 files alongside a short PDF memo that explains: • model assumptions...
