Analyze transitions 0% for a long time during the implementation of RT-BOX and c2000

Question

I am a little confused ,when I implement a very simple model with simple algorithm into the RT-BOX or c2000,it only takes a few seconds to comple the process ,but when the model is a little complex ,it almost can't complete the analyze process, the transitions analyze process is still 0% even after an hour,so what can I do to simplify the model and algorithm？

Answer 1

Could you describe your controller or circuit in more detail?

My suspicion is that you are using discrete switching devices instead of components from the Electrical + Power Modules section of the PLECS Library. 

Please refer to the RT Box Tutorials on the Plexim website for a complete description of why the power modules are useful.  The "RT Box: Timing and Step-Size Selection" tutorial will give a basic introduction to sub-cycle averaging concept and the power modules.  The "RT Box: Model Optimizations" tutorial will further explain the exact "Analyzing Transitions" error you are seeing and provide guidance on how to optimize your model.
