trim condition

Hi,

If you are speaking about the "planing regime" mode of the C-Wizard, you are able to impose a user-defined trim angle to your vessel in "Body configuration" section of the C-Wizard execution (i.e. the second graphical window appearing when executing the C-Wizard) . At the bottom of this graphical window, you have a menu named "Final position estimation" and there you can impose a user-defined trim angle. Note that the value should be entered relatively to the ship in its initial hydrostatic position and the rotation center used to apply the trim is the Center of Gravity defined in hydrostatic position (before applying the sinkage).

Hello my question is about displacement vessel not planing hulls , because when we do the simulation here we consider Ta (aft trim) , Tf (forward trim) so can u tell me where to specify in resistance case.

Hi, 

There is no option directly available from the "resistance mode" of the C-Wizard to input the vessel trim. If you want to compute at a specific trim value, it is better to apply this trim to your geometry and to import the trimmed model in the C-Wizard. Another possibility would be to define both the center of gravity and the body mass as "user-defined" and to define the option "Adjust pitch for hydrostatic equilibrium ?" on "Free". Doing this, the trim of the ship will be adjusted to its hydrostatic position, before meshing the vessel. This second approach corresponds to the definition of the CoG which corresponds to the desired trim.

Best regards,

Thank you for the info , is there any other way to specify it manually in the solver part?

Appart from those mentioned above, there is no other possibilities that will help you to impose a trim from the solver part.
