compute_FS

(chamberwise) switch to compute free surfaces (UCV)

Decide whether or not to check for free surfaces.

compute_FS = 'NON' # do NOT check for free surfaces (default) compute_FS = 'YES' # DO check for free surfaces

This parameter can also be set per chamber (see also KindOfProblem, CHAMBER)

compute_FS(1) = 'NON' # do NOT check for free surfaces, e.g. for air compute_FS(2) = 'YES' # DO check for free surfaces, e.g. for water

Note: The same parameter can also be set in common_variables. Definitions in USER_common_variables are dominant.

Default: compute_FS = 'NON'
