 ### Mesh Description
 
-The computational mesh for all domains consist of quads and can be generated through Gmesh. The .geo files for [Solid 1](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/solid_1.geo) and [Solid 2](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/solid_2.geo) describe a simple, square mesh with 40 nodes along each side. The .geo file for the [fluid domain](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/fluid_3.geo) contains refinement commands around the solid-fluid interfaces.
+The computational domain for this tutorial is made up of three separate meshes; [Solid 1](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/solid_mesh_1.su2), [Solid 2](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/solid_mesh_2.su2), and [Fluid](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/fluid_mesh.su2). The meshes for the solid domains are simple, square meshes with 40 nodes along each side, while the fluid domain mesh is refined near the interface with the solid domains. These meshes can alternatively be generated through Gmesh. The .geo files for [Solid 1](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/solid_1.geo), [Solid 2](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/solid_2.geo), and [Fluid](https://github.com/su2code/Tutorials/tree/master/multiphysics/contact_resistance_cht/fluid_3.geo) allow for the generation of the respective SU2 mesh files.
