I am having trouble getting the Modeler hull surfaces that I want to use for KNs to appear in Stability. They are set as "HULL" in Modeler but will not appear in Stability.
Check if correct surfaces are selected upon opening MAXSURF Stability. Select the surfaces that needs to be considered as hull shell.
Then if there is already a .hmd file with the loadcases, tank definition etc with the model. You can check/recalculate at any time from the analysis menu. This is to update the sections (without deleting the loadcases, tanks, etc) in case there are any changes to geometry.
