Known limitations and planned features
The limitations of the current NoviPath release in one list, with the article that explains each, and the features planned next.
The current release simulates one part per tray, takes loads and restraints in tray XYZ only, checks load/restraint overlaps only for Face selection, shows the outer surface only in the viewer, and estimates failure load linearly. Surface-normal and local coordinate systems, and the overlap check for Shapes, are planned.
The following limitations apply to the current release of NoviPath. Each links to the article that discusses it.
- One part per tray. NoviPath simulates a single part; if several models are on the tray, only the first model added is analyzed (Tutorial: your first simulation).
- Force and moment components in tray coordinates. Force and moment components are entered in the global (tray) X, Y, Z system. The Normal, Axis and Aim tools orient a load without computing components by hand, and Pressure always follows the surface normal, but a force or moment cannot be entered directly in a local surface coordinate system. (Applying Force, Moment, or Pressure.)
- Future versions are planned to support entering loads and restraints directly in local coordinate systems, for greater modeling flexibility and ease of use.
- Over-constraint check for Face selection only. NoviPath rejects a restraint face that already carries a load, but the equivalent check for Shape-based boundary conditions is not implemented in this version (Why doesn’t NoviPath always detect over-constrained setups before the solver runs?).
- Outer surface only in the viewer. The viewer shows the outer surface of the finite-element mesh and of the results; clipping by layer does not reveal the interior of the part (Tutorial: your first simulation, Display toggles and the 3D viewer).
- Linear-elastic failure load. Failure load = applied load / Max FI assumes linear elasticity and proportional scaling of the whole load set (Failure load, Failure index and safety factor).
- Memory guidance. Suggested mesh factors target a computer with 8 GB of RAM; finer meshes may need more (Controlling mesh size with edge factors, The simulation fails or runs out of memory).
Planned features
Support for entering loads and restraints directly in local coordinate systems, and an overlap check for Shape-based boundary conditions, are planned for future releases. This article is updated at each release.
