We have also changed the way that the number of stages is specified on the general data form. Giving the sequence of restarts distinct simulation times is also useful when showing replays and results as it provides a means of identifying each restart analysis within the sequence. when the model uses data that is time-varying, and the static analysis simulation time is used to look up values from the time-varying data. This is sometimes necessary for calculation purposes, e.g. This allows a sequence of static restarts to have distinct simulation times. Static analyses are now associated with a specified simulation time.The simulation can now be ramped down by specifying that the ramp finish time is before the ramp start time.These ramp times can even span multiple restart analyses. The dynamic ramp can now be performed between user specified simulation times.Very commonly such a sequence would use contiguous, increasing simulation times. Again, this allows a sequence of dynamic restart analyses to use distinct simulation times. The simulation time for the start of the simulation can now be specified by the user.This allows a sequence of dynamic restart analyses to use distinct numbers for their stages. The number of the first stage can now be specified by the user.To support the new restart analysis feature, significant changes have been made to the way that the simulation stage and time data is specified. Objects can even be created and deleted in the restart analysis. friction coefficients, object positions and even the masses of objects. This capability makes restart analyses much more powerful: in principle, every property of the model could be changed (although not all changes are permitted in practice), e.g. This is not simply the same as extending an existing model because the in built change tracking architecture allows for changes to be made to the model data before restarting. the positions of objects) as possible, before attempting to pick up where the parent analysis left off. Instead of simply running the model with the specified data, it will first load the parent simulation file and inherit as much state (e.g. A restart analysis behaves very differently to either. A standard OrcaFlex model behaves in exactly the same fashion as an equivalent variation model once the analysis begins they only differ in the way that the model data is presented to the user. Whilst a restart analysis tracks its changes against a specified parent model, in the same way that a variation model would, restarts are, from an analysis perspective, conceptually distinct from either of the other two model types.What is new in this version of OrcaFlex is the ability to prepare these variation models in the OrcaFlex GUI.
The basic functionality of variation models was available in previous versions of OrcaFlex (through text data files using the BaseFile identifier). Variation models use change tracking to identify those data items that differ versus the parent model.
A variation model is specified entirely in terms of the differences between itself and another OrcaFlex model, the parent model.A standard model is the type of model found in earlier versions of OrcaFlex.There are now three types of OrcaFlex model: standard models, variation models and restart analyses. We will, as always, attempt to fix any defects as quickly as possible. If you encounter any unexpected behaviour that you suspect to be a defect, please let us know. Whilst we have put in a correspondingly huge testing effort, we anticipate that some defects and issues remain. The restart analysis development represents a huge change to OrcaFlex, and affects almost every aspect of the software.
