What is the flow of the Modelling in COMSOL?

All turbulence models can be combined with the phase field and level set methods for two-phase flow in COMSOL Multiphysics. Two-phase flow with water and air in a reactor modeled using the level set method in combination with the k-e turbulence model.

What type of software is COMSOL?

multiphysics simulation software
COMSOL Multiphysics is a cross-platform finite element analysis, solver and multiphysics simulation software. It allows conventional physics-based user interfaces and coupled systems of partial differential equations (PDEs).

Which method is used in COMSOL?

Comsol is a finite element method software, so it uses FEM to numerically solve the differential equations.

What is level set Comsol?

The level set method is a technique to represent moving interfaces or boundaries using a fixed mesh. It is useful for problems where the computational domain can be divided into two domains separated by an interface.

What are the features of COMSOL Multiphysics tool?

General-purpose simulation software based on advanced numerical methods. Fully coupled multiphysics and single-physics modeling capabilities. Complete modeling workflow, from geometry to postprocessing. User-friendly tools for building and deploying simulation apps.

What is level set in COMSOL?

The level set method is a technique to represent moving interfaces or boundaries using a fixed mesh. It is useful for problems where the computational domain can be divided into two domains separated by an interface. Each of the two domains can consist of several parts.

How is dynamic mesh used in fluent?

Use the dynamic mesh capability of ANSYS Fluent to solve a simple flow-driven rigid-body motion problem. Set boundary conditions for internal flow. Compile a User-Defined Function (UDF) to specify flow-driven rigid-body motion. Calculate a solution using the pressure-based solver.

What is a free surface on Comsol?

The free liquid surface corresponds to the phase boundary between the liquid and the gas and is represented on a fixed mesh. The figure below shows the surface of two droplets in a channel, taken from the droplet breakup model in the Application Library of the add-on Microfluidics Module.
