Changes: MAXSURF Modeler
1095636: Generate NURBS surfaces from parts
NURBS surfaces can now be generated from any part in the design file (frames, decks, stringers, plates). The functionality is accessed from the Menu item "Surfaces | Add from visible parts...". This item is only enabled when a part or parts are visible in a drawing window. Adding a surface on a Frames/Bulkhead is a useful way to generate stiffened frames/bulkhead by being able to add a stringer on the generate surface.
1064114: Zebra mapping for continuity assessment of surfaces
A zebra map render option is now available from the render dialog:
Zebra mapping assists in generating extremely smooth NURBS surfaces helping to identify areas of discontinuity/poor continuity:
Bug fixes and minor changes
- 899068: Some improvements to the mouse interaction with the Surface Assembly window have been made.
- 899337, 899855: A model-specific surface trimming problem when going to Microstation dgn file format and back to Modeler msd file format has been fixed.
- 901076: Modeler is now able to calculate offset tables for Mesh surfaces (as it does for NURBS surfaces).
- 901335: The "Structure Sample_Workboat" model now includes part nesting and no longer gives a warning about the plates.
- 901346: Problems with surface trimming when different numbers of u, v parametric curves specified has been fixed.
- 901361: A problem with the Wolfson Import where y and z values were swapped has been fixed.
- 982415: When adding a curve, it is now possible to uses a Right-click context menu option to automatically close curve by making the last point coincident with the first.
- 1071888: Improvements to the cutout/punchout shape inserted into a frame where a stringer passes through it at an oblique angle have been made.
- 1084507: Merging US Navy and IMSA NURBS files into the current model is now possible
- 1095636: It is now possible to generate NURBS surfaces from parts (frame, deck, stringers and plates). This can be used to add stringers to decks for example. (Surfaces | Add from Visible Parts.)
- 1092273: Improvements to the algorithm to fit a Surface edge to a Curve have been made.
- 1099408: Material type and group properties of Meshes are now included in the exported Microstation dgn file format.
- 1100839 MOSES Modeler only: BEAMs whose geometry is defined by Curve or Stringers now support symmetry.
- 1107494: Holding down the Sift key when clicking the Render toolbar button now shows the same dialog as the Display | Render menu option.
- 1111489: The IGES NURBS surface export does now correctly mirrors the knot vector which fixes problems that caused incorrect trimming for surfaces with non-uniform knot vector.
- 1110797: The behavior and interaction with Stringer points for asymmetric Stringers is now consistent with the manipulation of Curve and Surface control points.
- 1127550: Improvements have been made to the method of adding Stringers on Surface contour curves.
- 1168444, 1177408: Significant improvements to the speed of the Mesh processing during model loading have been made. Since version MAXSURF 23.05 you may have noticed that models are slower to load, particularly if they contain many Parts (especially Stringers), Rooms (in the case of Stability) and large Mesh surfaces. This is due to older files not containing critical data relating to the Meshes and these data being calculated on the fly as the model is loaded. When you save in one of these versions, the critical data is included in the file, so subsequent model loading is much faster. However MAXSURF 2023 will load these models much more quickly than MAXSURF 23.05 or 23.06 due to the algorithm improvements included in MAXSURF 2023.
Changes: MAXSURF Stability
899436: Flood room when Key Point immersed, conditional flooding
It is now possible to conditionally flood a Non-Buoyant Volume (NBV). Normally NBVs are permanently flooded, this new feature makes it possible to flood the BNV only when a specific Key Point is immersed. This feature can be used to model the flooding of a yacht's cockpit for example. In the example below, some of the cockpit volume is below the waterline, however it is not considered flooded because the associated Key Points are not immersed. Then at 40deg heel the edge of the cockpit (modeled with a Key Point) is immersed and the cockpit is considered flooded. This step at 40deg heel, can be seen in the Descriptions of trim and draft against heel angle:
In this example, four Conditional flooding Key Points have been defined around the edges cockpit. the Type should be set to "Conditional flooding point" and they should be linked to the NBV which they will cause to be flooded when immersed. Since the cockpit has straight edges, this is sufficient to define when flooding will occur and capture the heel / trim combinations where seawater will start to slow into the cockpit. In this version of Stability, conditional flooding can only be applied to Non Buoyant Volumes (and not to Tanks nor Compartments). If you wish to have stability criteria which use the immersion angle of these points, then you must add extra Key Points at the same locations and assign them to the appropriate type (e.g. Immersion point).

899458: Classification of Key Points
There are essentially two basic categories of Key Points:
1. Key Points that are used purely to measure the angle at which they submerge or emerge during heel-based analyses (e.g. Large Angle Stability, Limit KG, Cross curves, etc). Or which are used to measure freeboard during equilibrium-based analyses (e.g. Equilibrium or Specified Condition).
2. Key Points which have a specific use within Stability: Water on Deck (WoD) freeboard points; Outflow points; and Conditional flooding points.The first category of Key Points may be grouped by Type so that they can be used in different stability criteria; normally the Key Point with the minimum (or sometimes maximum) value within the specified type will be used to evaluate the stability criterion. For example you may have (say) 10 downflooding points defined, then a criterion which requires the downflooding angle will take the minimum dowflooding angle of those 10 points.
In this version we have added a new type: "Weathertight opening". Thus the first category Key Points can be of type:
- Downfoolding point
- Potential downflooding point
- Embarkation point
- Immersion point
- Weathertight opening
For this first category of Key Points, their type is purely a way of grouping Key Points of different classification so that different stability criteria may be applied to different groups of Key Points. They do not have any special meaning
Bug fixes and minor changes
- 899370: A Crash which sometimes occurred when restoring Cross-Flooding results from the Stability results database has been fixed.
- 1083714 Available for Testing EngSim\Offshore\MOMAX\Stability Calculated required GM -incorrect units conversion for k1 CFR 46 170.170
- 1103151: Arrow heads are now drawn on the CG and CB vectors in the perspective view.
- 1117487: A problem which resulted in high memory usage in Stability for some models, particularly when doing Limiting KG analysis has been resolved.
Changes: MAXSURF Motions
1174547: Catamaran vs Monohull strip theory
A problem when analyzing a full catamaran model using strip theory was identified and fixed. When using strip theory to predict the heave and pitch response of a catamaran, interaction between the hulls is ignored *. For roll response, the effect of demihull separation is taken into account because this greatly affects the stiffness, radiation damping and added inertia in roll. The errors occurred because the full catamaran displacement and other hydrostatic properties were used when calculating response. This has now been corrected.
When using a simplified vessel model of a single demihull and specifying the demihull spacing imMotions, the problem did not occur, and consistent hydrostatic properties were used yielding correct results.
* Studies have shown that this interaction is small for catamarans with typical demihull spacing above all but the slowest speeds. e.g.: Molland, A.F., Wellicome, J.F. and Couser, P.R. 1995. Experimental measurements of the seakeeping characteristics of fast displacement catamarans in long-crested head-seas. University of Southampton, Ship Science Report No. 89, December.
When using the strip theory method to analyze the motions of a catamaran, the Hydrostatics dialog alwaysgives the hydrostatics of the single demihull (not the full catamaran). This is because the hydrodynamic properties are computed for the demihull in isolation.
Changes: MAXSURF Multiframe
Bug fixes and minor changes
- 899385: A dividing-by-zero problem in the AS4100 design check has been fixed.
- 901352: Using the same Description scale to different in x and y directions with Description overlapping has been fixed.
- 901359: Combined load cases of patch linear and edge loads are now correctly calculated.
- 915207: The issue of rendered members being drawn short has been fixed.
- 1059689: Incorrect maximum displacement displayed in deflection Description view has been fixed.
- 1076570, 1076694: Import of DXF and DWG files with multiple blocks now correctly applies the local coordinate system transforms to the geometric model.
- 1081349: An error with the rendered plate action not matching the results table values nor the linedrawing shaded Description color has been fixed.
- 1168439: A crash which occurred in SACS HullMesher if the expected section library file did not exist has been fixed.
