 ## Setup
 
 The expanding tube test case involves a cylindrical fluid domain surrounded by a solid domain. A pressure inlet boundary condition is applied at the inlet for 3 milliseconds, and then 0 set to zero for a further 7 millisecond. The pressure of the fluid expands the tube which then relaxes once the pressure decreases.

 ## Setup
 
 The setup for this tutorial is similar to the [flow over a heated plate](tutorials-flow-over-heated-plate.html) using OpenFOAM. In this tutorial OpenFOAM is used as the solver for the fluid domain, and code_aster is the solver for the solid domain. A difference here is that we are using a steady-state OpenFOAM solver for demonstration purposes, therefore the results between the two tutorials are not comparable.

 ## Setup
 
 This scenario consists of one fluid and one solid participant and it is inspired by Vynnycky et al. [1]. A fluid enters a channel with temperature $$ T_\infty $$, where it comes in contact with a solid plate. The plate is heated at its bottom and has a constant temperature of $$ T_{hot} $$.

 This tutorial describes how to run a conjugate heat transfer simulation with two separate OpenFOAM solvers and CalculiX. The files for this tutorial are located in this repository (directory CHT/heat_exchanger).
 
 This tutorial is based on [a case](https://www.simscale.com/projects/cheunglucia/heat_exchanger_-_cht_simulation/) prepared with [SimScale](https://www.simscale.com/) by [Lucia Cheung Yau](https://github.com/ludcila) for her [Master's Thesis](https://www5.in.tum.de/pub/Cheung2016_Thesis.pdf).

 ## Setup
 
 This scenario consists of two fluid and one solid participant and represents a [shell-and-tube heat exchanger](https://en.wikipedia.org/wiki/Shell_and_tube_heat_exchanger). The geometry includes an (adiabatic) shell, in which an _inner fluid_ flows. It enters from the top-right inlet and exits from the bottom-left, after getting redirected several times by baffles. The geometry also includes a set of tubes, in which an _outer fluid_ flows from left to right. The two fluids enter in different temperatures and exchange heat through the (thick) solid walls of the tubes. This is a steady-state simulation and the flow is considered laminar.

 ## Case Setup
 
 In the following tutorial we model a fluid flowing through a channel. Two solid, elastic flaps are fixed to the floor of this channel. The flaps oscillate due to the fluid pressure building up on its surface. In this case, a fluid and two solids are coupled together using a fully-implicit multi-coupling scheme. The case setup is shown here:

 ## Setup
 
 We have a rectangular linear elastic beam of dimensions 1 x 1 x 8 m, divided in two subdomains by a splitting plane at z = 6 m. This plane corresponds to the coupling surface. Both ends of the beam (z = 0 and z = 8 m) are fixed. A mechanical load F = -0.001 N is applied constantly along the y-axis onto a small set of nodes near the end of the beam. These boundary conditions can be seen in the input files `beam<x>.inp`. Initial conditions are zero both for position and velocity. Other parameters can be found and customized in the `.inp` files.

 ## Setup
 
 We solve a partitioned heat equation. For information on the non-partitioned case, please refer to [1, p.37ff]. In this tutorial the computational domain is partitioned and coupled via preCICE. The coupling roughly follows the approach described in [2].
