Alibre Design

Chapter 19 - Alibre Motion• AVI Generation – Generating AVI's will slow playback perormance, and theamount to which they do so will vary greatly depending on the Video Handler orCODEC, that you use.19.6.8 Simulation WarningsWhile reading your Assembly design, and also before and during simulation, there maybe times when Alibre Motion detects a condition which may affect the accuracy or someother aspect of the Simulation you wish to perform.For instance, you will be warned when any Moving Parts in your assembly haveextremely high or low densities, as this may be an indication that the results you getwill not be realistic. In all of these cases, the Motion Status window opens automaticallyif it is not already showing, and the warnings are displayed. If you are satisfied that thesituation described is as you intended, you can close the window, and ignore themessages, if you so choose.Simulator MessagesJust before and during Simulation, the Alibre Motion Simulator displays variousmessages showing its status, and the progress of the simulation calculations. These aredisplayed in the bottom half of the Motion Status Window (unless you have turned themoff by unchecking Show Simulation Messages on the General Tab of the Settingsdialog). In some situations, such as when you specify a prescribed motion that cannotcontinue, the Simulator will stop, and display various messages here. If the Simulatorstops for no apparent reason, make sure that the Simulator messages are visible, asthey often provide useful feedback about what has happened, and what may be done tocorrect the situation.‣ To turn on and off the Motion Status window:1. From the Motion main menu, check the option Show Status Window to turn iton, and uncheck the option to turn it off.19.6.9 Maintaining Multiple SimulationsMultiple SimulationsAlibre Motion allows you to maintain multiple Simulation Setup’s for each Configurationin your Assembly design. Each Simulation may have completely different Motors,Motions and Effectors, with different Traces, Measurements and Simulation andPlayback settings specified. Using this feature you can try out multiple scenarios with,for instance, different strength motors, and compare the results from each.557
