(Toolbox fOr Stratified Convective Atmospheres)
TOSCA is an incompressible finite-volume large-eddy simulation code formulated in curvilinear coordinates with Boussinesq approximation to account for buoyancy. It features a moving immersed boundary method and several actuator models to include bodies and wind turbines within the simulation domain. It has been successfully used to simulate atmospheric boundary layer and wind farm flows, including terrain and wind farm induced atmospheric gravity waves, cluster wakes, as well as wind farm control problems. TOSCA is currently developed at the Computational Fluid Dynamics Laboratory of the University of British Columbia, Okanagan Campus.
We kindly ask you to please fill up this survey, which allows us to keep track of new TOSCA users around the world.
A large effort has been recently put in creating a comprehensive User Guide, which hosted right here on GitHub.
Although some chapters are still under construction, you can already find instructions on how to install the code, a complete list of all input files and variables, together with their explanation,
as well as a step by step guide of some of the tutorials that are available on the repository under the tests/ directory. We refer to these set of
read-the-docs pages online as the main TOSCA user guide.
An additional, temporary, user guide (which will soon become outdated) with a TOSCA Getting Started can be found inside docs/ (TOSCA_UserGuide.pdf).
For programmers, the code follows the Doxygen commenting style, so that a programmer's documentation is automatically generated by Doxygen.
This can be found both inside docs/ (ReferenceManual.pdf), or opened as a web documentation upon downloading the TOSCA repository and opening
docs/html/index.html
For bugs, questions and to request modification to the TOSCA code, please open an issue GitHub. You can also contribute to the TOSCA code as explained here. For different matters, please contact [email protected] or [email protected].
