:::{admonition} Wall bounded / multiphase / reactive flows ...?
Maybe. The built-in {mod}solvers <fluidsim.solvers>
excels solving within
periodic domains with pseudospectral solvers. However, FluidSim is a framework,
and this allows FluidSim to interface with third-party solvers. See for
instance {mod}fluidsim.base.basilisk
, {mod}fluidsim.base.dedalus
and
snek5000.

Make sure you read the installation guide carefully.
:::{admonition} Permission denied while running pip install fluidsim
from PyPI or make develop
inside the repository.
This means you are probably using the Python bundled with the system and as a user you are restricted from installing packages into it. If this is so, create a virtual environment.
:::
:::{admonition} No module named pip or distutils.errors.DistutilsError
Package manager pip
was not installed into your environment or is too old. The
following commands should help:
python -m ensurepip
python -m pip install --upgrade pip
:::
:::{admonition} System freezes or becomes unresponsive as fluidsim starts to build extensions
By default pythran
extensions try to use gcc
and this is a
CPU and memory intensive compilation. Instead pythran
can be configured to use
clang
. See {ref}pythranrc
for more details.
Additionally to reduce the load during installation one can limit the number of parallel processes used to build extensions.
:::
:::{admonition} ModuleNotFoundError: No module named 'fluidsim_core. ...
FluidSim depends on {mod}fluidsim_core
and both follow the same versioning. Make
sure the versions match if you had used pip install
or conda install
. For
developers, make develop
should install both as editable installations.
