Hey everyone,

I would like to present a tool for the generation of two-dimensional unstructured grids, which I programmed in the last months. It was actually a little side project during the Covid pandemic, in order to learn C++ programming. However, I thought that there might be someone who could have a use for it - maybe for educational purposes e.g. to create simple grids for CFD seminars or to test simple CFD solvers written from scratch.

The grid generator is called TQMesh and you can have a detailed look on it on Github:

https://github.com/FloSewn/TQMesh

The application is run from the command line and currently I only tested it on linux (sorry to all windows / mac users). It is basically a header-only library, so one could use it in other C++ applications.

I am happy for feedback, reports on bug or even on anyone's contribution

Greetings
Flo

It will br very useful for me because i am passionate about this.

Hi, I am doing my final year university project. Studying the effect of air flow on the triangular cylinder. I am required to use openfoam. May I ask you, how to implement the unstructured mesh on my project ?

Hey there,


unfortunately the output format is currently not yet suitable for OpenFOAM. But I will try to implement it in the future.

At the moment I'm in holidays but in a couple of weeks I would like to use your meshing tool inside my caseBuilder, a graphical tool to realize openfoam cases. Till now it was not yet published, and may be I'll change the name in flowBuilder to avoid confusion with silentDynamics product.

Dear Flo,

I need a quad mesh of a simple round cornered rectangular cross section with a certain thickness (so to say with a similar inner mesh). Is it possible to define the outer mesh based on lines and arcs ?

kind regards,
David

Hey David,


sorry for my late response.



Unfortunately, at the moment it is not possible to specify such a geometry directly.

However, with the latest release you can define mesh boundaries by coordinates, which can be imported as CSV files. So you could create the geometry by another program and then simply read it into TQMesh.

Thank you for the clarification. I will use gsmh. David
