Regarding probablity damage stability

Immersion angle fails & invalid parameters showing ...........why

  • This is a bit hard to guess just from the single table.

    My two guesses here are:

     - The Invalid parameter is because the vessel immersion angle is -ve for those load cases

    - All of the other cases have an immersion angle of zero. That doesn't seem right. I think there is an issue with the model. Have you already tested this vessel for upright and deterministic stability?

    I would first be looking to see if the deck edge and margin line  definition was correct and doesn't accidentally go below the waterline at upright. Use Display | Visibility | Margin Line

    When troubleshooting probabilistic cases, you can copy individual (or all of them if none are selected!) cases to be deterministic cases and then analyse the cases that way. This lets you visualize the vessel at each point of the analysis which helps to track down issues easier.
