We have just released a minor upgrade to OrcaFlex, version 11.3d. Version 11.3d fixes a number of bugs, including a significant bug affecting the contents density results variable when using the line slug flow contents method.
Full details of the changes are described in the documentation:
We recommend that all users of 11.3 upgrade to 11.3d.
