![]() This project gets around potential case-sensitivity issues by putting OpenFOAM itself inside a (read-only) disk image with its own case-sensitive filesystem, which is mounted as a virtual volume during use. In contrast, a case- insensitive filesystem, as is the default on macOS, will only allow one of those files to exist in the same folder. In practice, a case-sensitive filesystem means that two different files named phi and Phi in the same directory can exist just fine. This is a non-issue on Linux systems, which conventionally use case-sensitive filesystems. OpenFOAM is notably developed with a case-sensitive filesystem in mind. The default macOS filesystem is case-insensitive, which differs from Linux. If your code was never tested with Clang before, some lines might require a little tweaking ( this is the most common fix that is needed) to be able to build across both compilers. The compiler used on macOS is Apple's Clang, which is not the same as the GCC compiler used by default on Linux. See here for an example of a project that installs this way. The right way to install additional solvers and libraries is to place the binaries in $FOAM_USER_APPBIN and $FOAM_USER_LIBBIN respectively. This is very much intentional (and is similar with how it works with packaged OpenFOAM on Linux). The OpenFOAM installation itself is not user-writable. Can I compile and install my own (or third-party) solvers? If you're installing with Homebrew, the suggested -no-quarantine option does this for you on install. You only need to do this for the first launch of the app. You can tell macOS to allow the app to run by right-clicking on the app in a Finder window and selecting Open from the context menu. ![]() ![]() This message appears because the app is not notarized by Apple. Why do I see a dialog that says the app "cannot be opened because the developer cannot be verified"? Get the native macOS version of ParaView from the official site or install with Homebrew (prefer the latter if you'd like to use OpenFOAM's paraFoam command).
