Modeling a Sphere Falling on a Water Surface
This model shows modeling of a sphere falling on a water surface. Specifically, it models the oscillating motion of a buoyant sphere as it falls through air and interacts with the air-water interface to finally float on water. Get more details in our blog post: Modeling a Sphere Falling ... Read More
Connecting Beams and Solids
This example demonstrates the use of the Solid-Beam Connection multiphysics coupling to create transitions between the Solid Mechanics and Beam interfaces. Two different connection types are discussed, and a comparison of the stress distributions at the transition is made. Read More
Shape and Topology Optimization of an Extruded Beam
This model demonstrates 3D topology and shape optimization for an extruded geometry. This can be achieved using equation-based modeling and extrusion operators. The model considers stiffness maximization of a beam subject to a constraint on the mass, but the method can be used with any ... Read More
Sierpinski Fractal Monopole Antenna
A fractal is a mathematical form showing self-repeating patterns. By virtue of its geometrical properties, a fractal structure can generate multiple resonances in RF applications. This antenna model uses a 3rd order Sierpinski triangle and the calculated S-parameters shows good input ... Read More

This model simulates a static analysis of heat conduction in a thin conductive shell. This is a benchmark model where the result is compared with a NAFEMS benchmark solution. Read More
Switched Reluctance Motor
Switched reluctance motors work on the principle of reluctance torque. The stator and rotor will interact so as to minimize the reluctance for the flux path. This application simulates the behavior of the motor when the stator winding is excited with a step voltage and the rotor being ... Read More
Tire Inflation
This model showcases how to use fibers in thin layers to model thin anisotropic composites embedded in a solid without explicitly drawing either the layer of material or the reinforcing fibers. Here, it is used to model steel cords in tire belts that are used to provide structural ... Read More
Heat and Moisture Transport with Mold Growth Prediction
This tutorial demonstrates how to use the temperature and relative humidity computed by the simulation of heat and moisture transport in an insulated roof as inputs for a mold prediction model. The VTT model for mold growth and decline prediction computes a mold index M by solving an ... Read More
