Simulink’s rapid accelerator mode is designed to speed up the simulation of models by compiling them into a standalone executable. This mode can significantly reduce simulation time, especially for large or complex models. However, there are several reasons why Simulink might not work or fail to simulate a model in rapid accelerator mode like unsupported blocks or features and model configurations or parameter issues.
For more information related to rapid accelerator limitations, you can refer to the below documentation links-
