How to set initial values in COMSOL Multiphysics

There is a critical importance for initial values which the domain cells gained at the beginning of solving process. IN COMSOL Multiphysics we set these values via Initial Values section. In this tip Simulation of Supersonic Air-to-Air Ejector CMS is used to illustrate this tip and we will set velocity and pressure as initial values.

Initial Values 1

  1. In the Model Builder window, click Initial Values 1.
  2. In the Settings window for Initial Values, locate the Initial Values section.
  3. Specify the u vector as
0r
100z
  • In the p text field, type 2[atm].
01 - Set Initial Values


CMS

Computational Modeling and Simulation is the simulation center of Acamech that models Mechanical Engineering Problems, especially Multiphysics Simulation; including Fluid Flow (CFD), Structural Mechanics, Acoustics, Heat Transfer as a unique Multiphysics problem. We use COMSOL Multiphysics, MATLAB, and Autodesk Inventor.
