Issue when importing External Damping matrix and External stiffness matrix from Wamit to Rosetta.

[Cesar-dotcom]

Hi @izabala123

I have noticed that the import process for the External Dimensional Damping Matrix (EXDAMP) and the External Dimensional Stiffness Matrix (EXSTIF) in Rosetta is wrong.
In the pictures below you can see the two matrices. In this case, what I expect to be the Additional Linear Damping Matrix is placed in the Mooring Stiffness Matrix and vice versa.

I am also attaching a screenshot of the Force file from Wamit.

Thank you in advance for all the great work on this software!

Hi Cesar

Thanks for your comment.
I'm confused because so far the .frc reader doesn't read EXSTIF fields. It is added now.
Please confirm that the BEMRosetta views have been obtained by reading the file in the screenshot shown.

Best regards

Hi Iñaki,

You are right, when uploading the .frc file in BEMRosetta, it only reads the EXDAMP matrix and does it correctly. However, I have to do it in a separate folder, not in the project folder.
If I do this in the project folder, when uploading the .frc file, the same happens in the screenshots I attached in the issue at the beginning. It seems it uploads information from the whole project folder because it also loads Added Mass and Damping, load RAO's and motion RAO's.

Best regards

Hi Cesar

Yes, that's it. Wamit spreads the info in different files so, depending on the file you give BEMRosetta, it does different things:

• .out: This includes all. BEMRosetta doesn't care of other files.
• Any other file: BEMRosetta reads all available files in that folder trying to pick up all the data.

If you have any problem please send a sample file or set of them and I will solve it immediately.

Best regards
Iñaki
