This repository contains examples for using and testing svFSI. Examples are organized based on the physics solved. Each example folder has multiple cases with several options that include boundary conditions, linear solver settings, etc. User are encouraged to review svFSI_master.inp for a detailed description of the input file and its settings.

A description of each example is provided within the folder. Examples include:

1. heat: diffusion equation solver

2. lelas: linear elasticity

3. stokes: Stokes flow

4. fluid: incompressible flow (Navier-Stokes equation)

   1. pipe3D_RCR: pipe flow with RCR boundary condition
   2. dye_AD: dye transportation with fluid flow
   3. driven-cavity-2D: 2D driven cavity flow
   4. 3D0D-coupling-BC: generic boundary condition that couples 0D model to 3D flow
   5. nonNewtonian: Carreau-Yasuda and Casson non-Newtonian flow
