Introduction
This tutorial steps you through the process to create a mesh for hydrodynamic modelling with TUFLOW FV. We will:
- Build a trapezoidal channel mesh.
- Build a river channel mesh.
- Provide you with background on the meshing process in TUFLOW FV.
- Link you to further tips and tricks and meshing learning resources.
Assumed Knowledge
No prior knowledge is required for the completion of these tutorials. We have designed this tutorial to provide an introduction to meshing for all modelling levels. Therefore, each step will be clearly explained. If you run into any problems or need help, please contact support@tuflow.com.
Meshing Guidance
The primary goal when designing a flexible mesh is to describe the key bathymetric and hydrodynamic features using the least, largest mesh element sizes possible that still provide adequate resolution for the problem you’re trying to solve. This is a key benefit of flexible meshes; to optimise computational efficiency whilst achieving desired model accuracy.
Creating a mesh is a combination of manual and automated steps. Maintaining a reasonable amount of manual intervention into the design of the mesh will ultimately produce a far more efficient mesh which will be more accurate and computationally efficient.
TUFLOW FV solves its equation set on regular structured grids or unstructured meshes. When building a model we typically take advantage of the flexible mesh capability and meshes can be comprised of triangles only, quadrilaterals only or a mix of triangular and quadrilateral elements. The flexible mesh approach allows for seamless boundary fitting along complex coastlines or open channels as well as accurately and efficiently representing complex bathymetries with a minimum number of computational elements. The flexible mesh capability is particularly efficient at resolving a range of resolutions within a single model without requiring multiple domain nesting.
In the meshing tutorials that follow, we will start with relatively simple meshing tasks, and then build up complexity so that you will have the tools you need to work on your own projects.
