The strength reduction technique is a tool to find the factor of safety (FOS) in geotechnical problems, particularly in slope stability analyses. To determine the factor of safety of the slope, the strength properties in the Mohr–Coulomb model are gradually reduced until failure occurs. ... Read More
This tutorial model explores the behavior of a microwave plasma torch. The plasma is generated within a dielectric tube inserted in a rectangular waveguide. The simulation solves the coupled equations for plasma transport and heating, microwave electromagnetic fields, fluid flow, and ... Read More
This tutorial studies the deposition of amorphous silicon using an inductively coupled plasma reactor with a silane/argon gas mixture. It examines how the deposition rate varies across the wafer as a function of silane mole fraction and input power. Read More
This model demonstrates an efficient approach to simulating a thin, spherical, large radome using a 2D axisymmetric formulation with cubic discretization. The axisymmetric method captures full 3D behavior for azimuthally symmetric geometries at only a fraction of the computational cost. ... Read More
