Ansys Jobs

I need a skilled Ansys HFSS user to run full-wave simulations on an antenna design and provide clear Return Loss (S11) results. This is a simulation-only assignment—no fabrication or physical testing for now. What I will share • Geometry or sketches of the antenna and the target frequency band. • Any material data or performance goals I already have. What I need back • The HFSS project file (.aedt) with all boundaries, excitations, and mesh settings correctly defined. • A PDF or image plot of S11 versus frequency that clearly shows the return-loss performance across the band. • A brief note (one page is fine) explaining solver settings, boundary conditions, and any tuning steps you took. At the moment, the exact antenna style is open; experience ...

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...
