Issues with stability calculations.
1. Tank modelling
2. Loadcase definition
Make sure that at least one loadcase is defined. Loadcases define the loading condition of the vessel. Static weights that make up the vessel lightship are specified here as well as tank filling levels, expressed as either a percentage of the full tank capacity or as a weight.
3. Stability criteria not defined
See Stability Criteria Approach
4. Hull model on the port side
Usually when the model is imported from other software, there is a difference in the coordinate system. As a result, the model is on the port side instead of the starboard side. Before working in Stability, make sure that your surfaces have positive offset values.
In order to check if your offset values are positive, go to MAXSURF Modeler | Window | Control Points.

5. Surfaces with wrong directions
All surfaces should point outwards. The surface direction may be inverted by clicking on the circle at the end of the arrowhead. This is important for rendering, skin thickness direction, and correct interpretation of the design when it is loaded into Stability or Structure.
