Introduction : What is Comsol Multiphysics ?3:53
Master the basics of modeling with a standard single workflow in Comsol Multiphysics, covering model setup, materials, physics, mesh, and post-processing.

Set Up Model1:07
Open a new model, use the model wizard to select structural mechanics, add the physics, and set a stationary study for stress-dependent elasticity.
Ceate Geometry1:10
Create a geometry by selecting the geometry option, choose the rectangle primitive, enter a width of 10 cm, right-click the rectangle to select it, and zoom in or out.
Set Up definitions1:14
Configure definitions and functions in COMSOL Multiphysics by locating the step function under step type and editing parameters in text fields, then inspect the transition zone size in solid mechanics.
Adding Physics3:55
Set up physics in COMSOL Multiphysics by selecting boundaries, applying boundary loads, and fixing constraints, then configure domain contributions and define an auxiliary dependent variable P.
Adding Materials1:19
Define material properties in the model builder by selecting blank materials, setting density to zero, and entering values for Young's modulus and Poisson's ratio in the materials content.
Meshing1:12
Configure the mesh in the baldor model by right-clicking the mesh, selecting boundary distribution, entering 20 in the distribution window, and applying distribution across the world.
Study & Post Processing Results4:01
Perform post-processing by computing the selected step, inspecting stress and Young's modulus for the solid, and displaying the transformation through the beam's thickness via a cutline and line graph.

Part 11:54
Choose to start with a model wizard or an empty model, then explore two-dimensional setup and the physics window to add electrical circuit interface or fluid flow for multiphysics simulations.
Part 21:20
Navigate the fluid flow branch and fluid-structure interaction, select a time dependent study, and follow the model builder steps to complete your COMSOL Multiphysics model.
Part 34:15
Create and modify geometry in Comsol by selecting primitives like circle and rectangle, specifying coordinates and dimensions, then use union and object selection to define boundaries for physics.
Part 44:10
Explore configuring a comsol multiphysics model by defining geometry, applying mesh, and setting up laminar flow with domain one, stabilization, boundary conditions, and inlet velocity parameters.

Description

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). COMSOL provides an IDE and unified workflow for electrical, mechanical, fluid, acoustics, and chemical applications.

Several modules are available for COMSOL categorized according to the applications areas Electrical, Mechanical, Fluid, Acoustic, Chemical, Multipurpose, and Interfacing.

Fluid-structure interaction (FSI) is a multiphysics coupling between the laws that describe fluid dynamics and structural mechanics. This phenomenon is characterized by interactions – which can be stable or oscillatory – between a deformable or moving structure and a surrounding or internal fluid flow.

When a fluid flow encounters a structure, stresses and strains are exerted on the solid object – forces that can lead to deformations. These deformations can be quite large or very small, depending on the pressure and velocity of the flow and the material properties of the actual structure.

If the deformations of the structure are quite small and the variations in time are also relatively slow, the fluid's behavior will not be greatly affected by the deformation, and we can concern ourselves with only the resultant stresses in the solid parts. However, if the variations in time are fast, greater than a few cycles per second, then even small structural deformations will lead to pressure waves in the fluid. These pressure waves lead to the radiation of sound from vibrating structures. Such problems can be treated as an acoustic-structure interaction, rather than a fluid-structure interaction.
