Trim optimization

Question

Hello, I am trying to find out the dynamic trim on my simulation but when the window opens with the dynamic trim displayed, it is always at 0&deg;. Can you tell me where the problem comes from and how to solve it. Before I have this message "DomHydro could not compute the parameters. All of them are set to 0.". This is in C-Wizard modul.

Hi aupetit24250, 
 If the Domhydro tool is already not able to compute the parameters, there might be some issues with your domain (geometry). Did your mesh generate correctly and did the computation run as expected? Could you check whether the body is defined correctly in the Body definition menu? If Domhydro failed to calculate the parameters, it will also not have set the correct mass, CoG and inertia matrix values, so I doubt the computation has run correctly. 
 In order to help you out, it would be really useful to also have a look at the cwizard.log file in the project folder, as well as the domhydro.out file in the _mesh folder. You might also want to verify that you're not using nonstandard characters in the project name and check the documentation 3 
 Kind regards,
