Electrical Harness Process Simulation (EHS) - P2

 

General Issues

Real Time Cable Move
After you start a Real Time Cable Move, you cannot change the connector you want to manipulate if it is not on the same cable. Cross-highlighting will also not be updated if you change connectors/clamps on the cable from the dialog.
Multi-Cable Move
Multi-Cable Move Activity creation is disabled. Multi-Cable Move command can be used to move multiple bundles interactively (like the real-time move command for single bundles).
  If you move a harness too far from its initial position, reset might not work with realistic solver mode. This is a limitation.
Visualization
When the main bundle is moved, some of the cylinders of the main bundle seem to be missing. This is, however, only a visualization problem and does not reflect the overall capabilities of the command.
  When you move a connector and an error condition occurs (such as stretching the cable too far), the fixed/free constraint icons move.
Working in Cache Mode
In Cache Mode, you should have the following Tools Options setting for EHS to work: Digital Process for Manufacturing > Tree tab > Hierarchy tree section > Check Applicative Data check box.
Child moves parent
When a child bundle is moved, the parent bundle will not be affected.
Moving a connector
If you move a connector too quickly with an ICIDO solver enabled, you may have issues such as broken cables.
Free clamps on a moving cable
When you are working with the ICIDO solver enabled, you may see the cable jump around if there are free clamps on the moving cable. This does not affect the clamp positions or the connector positions, only the cables.
V4 support
Not all migrated V4 models will work.
Engineering control points
When working with ICIDO solver, Engineering control points are treated like user defined control points. Original position of ECP’s are not respected. ECP’s will instead follow the solver defined shape.
Home position
You cannot select a product after selecting the Home Position command, but you can select the 3D bundle or the simulation item under the desired bundle.
CAA Interface
DNBIEHSCableSimulation::GetPosition The returned positions are global coordinates, not relative to the cable. This differs from R19sp6.

Open Issues

During build or during sudden change in the position of the connectors, the cable will have a sharp bend in its shape but error notification will be given to the error
The ICIDO solver is supposed to give us an error code when it fails to make a solution. In some cases it does not, probably because whatever criteria it uses to make that determination does not succeed in some specific cases. So it comes back saying the shape is ok, which causes V5 not to display the error. If the error code was correctly set, we would iterate and try to find a better solution and if we did not succeed, we would report a error to the user.

Using Environment Variables
A new page has been added to the Customizing section, describing how to use environment variables to make your use of EHS more effective.
