Description 
Dynamic Solver Settings  
RealTime.SyncClock  Tickbox  
RealTime.On  Tickbox  SysCAD will solve the model at a speed relative to the time on your PC. If the RealTimeMultiplier is set to 1 (100%), then it will take 1 second of running time to simulate 1 second of real time. 
RealTime.Multiplier  Input  Multiplier of time when using the RealTime option. If the RealTimeMulitplier is set to 2 (200%), then it will take 1 second of running time to simulate 2 seconds of real time. 
StepSize  Input  The size (time) of each step. A higher value results in a faster relative speed, but generally a less accurate solution. The maximum step size that can be used is dependent on the dynamics of process (relative flow rates, volumes of units, timing of events, etc). A single step can have multiple iterations to solve the flowsheet and associated controls, similar to solving a steady state project. The maximum number of iterations per step is set on the Tears tab . 
StepSize.Min  Input  Minimum step size. 
StepSize.Max  Input  Maximum step size.

Method  Input  The method used for the dynamic simulation can be changed here.
