discovery

Discovers Comsol installations.

This is an internal helper module that is not part of the public API. It retrieves information about installed Comsol versions, i.e. available simulation back-ends, and locates the installation folders.

On Windows, the discovery mechanism relies on the Registry to provide information about install locations. On Linux and macOS, Comsol is expected to be installed at its respective default location. Though the folder .local in the user’s home directory is also searched to allow symbolic linking to a custom location.

In a last step, we also run the shell command where comsol (on Windows) or which comsol (on Linux and macOS) to find a Comsol installation that isn’t in a default location, but for which the Comsol executable was added to the executable search path.

Note that duplicate installations will be ignored. That is, a Comsol installation found in a later step that reports the same version as one found in an earlier step will be ignored, regardless of install location.

parse(version)

Parses version information as returned by Comsol executable.

Returns (name, major, minor, patch, build) where name is a string and the rest are numbers. The name is a short-hand based on the major, minor, and patch version numbers, e.g. '5.3a'.

Raises ValueError if the input string deviates from the expected format, i.e., the format in which the Comsol executable returns version information.

search_registry()

Returns Comsol executables found in the Windows Registry.

search_disk()

Returns Comsol executables found on the file system.

lookup_comsol()

Returns Comsol executable if found on the system’s search path.

find_backends()

Returns the list of available Comsol back-ends.

backend(version=None)

Returns information about the Comsol back-end.

A specific Comsol version can be selected by name if several are installed, for example version='6.0'. Otherwise the latest version is used.
