Step and produce the blockMeshDict programmatically with a nice Python APIĪnd a nice mechanism to add and store parameters. Tutorial is produced with the blockMesh OpenFOAM utility and theīlockMeshDict is quite complex and contains a #codeStream directive (which Produce some input files programmatically. But this solver can very easily be improved to be parametrized and to The simulation described in the Flow around a This command creates a solver fluidsimfoam-cylinder that can be used to run For example, to produce a solver from an existing case, one can run fluidsimfoam-initiate-solver cylinder -c $FOAM_TUTORIALS/basic/potentialFoam/cylinder There are open-source solvers (some of them are included in our mainĪnd it is not be difficult to write your own solver based on your OpenFOAMĬases. load simulations, read the associated parameters/data and produce nice figures/movies.launch/restart simulations with Python scripts and terminal commands,.Aįluidsim solver is a small Python package describing a set of simulations.įluidsimfoam allows one to write Fluidsim solvers based for the simulationsĪs shown in our tutorials, with a Fluidsimfoam solver, it becomes very easy to " solver" and "OpenFOAM solvers" are very different things. Jinja templates) in a small Python package that we call a " Fluidsim solver". Theĭescription of one set of simulations is done in Python (and possibly with (as shown in the OpenFOAM tutorials), but sets of similar simulations. With Fluidsimfoam, we introduce the possibility to describe not only one case The method described in the official OpenFOAMĭocumentations is to copy an existing simulation directory and to modify the Working with OpenFOAM implies writting and modifying a lot of input filesĭescribing a simulation. However, Fluidsimfoam is not restricted to these usages and should beĬonvenient, especially for people knowing Python, for any OpenFOAM usages for programmatic control of a simulation at runtime (an example.programmatic generation of complex and parametrized input files (for example blockMeshDict) and initial conditions,.automatisation of simulation launching for example for parametric studies or optimization,.It only uses OpenFOAM commands on the backgroundįluidsimfoam should be especially useful for: Possible to come back to the standard OpenFOAM workflow.įluidsimfoam can be seen as a workflow manager for OpenFOAM or a Python However, experienced OpenFOAM users won't be lost becauseįluidsimfoam produces in the end standard OpenFOAM cases and it's always Withįluidsimfoam, we try to design and propose a new workflow for OpenFOAMīased on Python. OpenFOAM is a very popular open-source C++ CFD framework.
