Only this version is now still in maintance, make sure to use this as if you have GPU.
You can use it to initialize a 3D boat with an arbitary function and to add ballasts and masts to your boat.
After this, you will be able to calculate the center of mass and center of buoyancy of your boat, with which you can obtain its waterline and righting moment.
In the end, the program will tell you whether your boat is stable and give you some instinct results.
The boat test video is here: https://drive.google.com/open?id=1xxnOqMBaFyNcgnLHjJZ1gzvoHRIJBtvC
All the 3D print source files you need, including solidworks file, STL generating tools written with matlab(This program is modified on other people's work), gcode file that could be printed directly on Ultimaker, are here: https://drive.google.com/open?id=1Zk6Com191bygU-sJWlvQdeYMoig3mTV4
You can also find a part of this in /3D print folder due to the space limitation.
I know very clearly that this program is still far from maturation. If you have any questions or find any bugs, please feedback to me via email lwangcg@connect.ust.hk

It's not permitted for students in HKUST's QEA class to copy any part of this code directly before they submit their code, or it will be treated as cheating.
