COMSOL Multiphysics® | Tips & Tricks – Parameters

Parameters are extremely helpful throughout the modeling process.
Addressing dimensions in the Geometry, assigning Input Values or changing Material Constants
– all easily set up and quickly changed in one place using Parameters.
Moreover, Parameters enable Parametric Sweeps in conjunction with your studies.

This Tips & Tricks clip shows you how.

COMSOL Multiphysics® | Tips & Tricks – Variables

While Parameters are fixed for a given simulation run, Variables can change.
They thus enable active inputs and dynamic feedback to your simulation.
For example, temporal and spatial distributions or other dependencies based on a current value during the simulation.

COMSOL Multiphysics® | Tips & Tricks – GPU Acceleration

COMSOL Multiphysics® 6.4 expands the GPU acceleration capabilities to all areas of physics with the new NVIDIA CUDA® Direct Sparse Solver - cuDSS - which is optimized for hybrid CPU–GPU computation and can be used with all recent NVIDIA® graphics cards. Using cuDSS is particularly beneficial for modeling scenarios where direct solvers are already in use.

This Tips & Tricks clip shows you how to implement GPU acceleration via cuDSS in your model.
