Model Vortex Lattice Formation in a Bose–Einstein Condensate
Bose–Einstein condensation can cause superfluidity, superconductivity, lasers, and trapped dilute cold atoms. When such systems are subjected to rotating perturbation, it forms a vortex lattice.
Equation-Based Modeling with a Space-Time Discretization
In COMSOL Multiphysics®, almost any expression in a computational model can be modified. For example, using a space-time discretization can make optimization problems easy and fast to implement.
Implementing a Damage Evolution Law for a Hyperelastic Material
By implementing a physically motivated damage evolution law for a hyperelastic material, you can incorporate material softening, creep, and stabilization of hysteresis curves during cycling.
Estimating Hyperelastic Material Parameters via a Lap Joint Shear Test
For rubber, polymers, and biological tissue, the relationship between stress and strain is nonlinear, even at small loads. The lap joint shear test can be used to determine material properties.
