Strategies to Counter Small Automatic Time Steps
When solving a model, you may encounter a varying time step and discretization order, or NLfail or Tfail could be greater than 0. Use these strategies to improve the efficiency of the simulation.

Happy Birthday, Olga Ladyzhenskaya
Olga Ladyzhenskaya wasn’t one to shy away from a challenge. In fact, through her research, she proved the convergence of a finite difference method for the Navier–Stokes equations.

Thermal Equilibrium and Nonequilibrium Heat Transfer in Porous Media
Heat transfer in porous media can occur under thermal equilibrium, such as a rock consisting of different minerals or trapped fluids, or nonequilibrium, like a thermal energy storage (TES) unit.
