Simscape Asynchronous Machine block doesn't work in accelerator mode with C++

The asynchronous machine block doesn't work in in accelerator mode if the language is set to C++

The error looks like this:

This error is easy to reproduce in any model that contains this block. I reproduced it with MATLAB's Three-Phase Asynchronous Machine example. I opened this example with Simulink online and set accelerator mode and language to C++, then I had this error.

It seems that this model still works with C. I have also checked the MingW 64 compiler was properly configured by mex -setup. Please tell me how to solve this issue, or if this block is simply not supported in C++?.

Hi @Shu,

To resolve the error, you should enable Verbose accelerator builds in the model configuration pane and navigate to the Simulink target. For further guidance, you can refer to following documentation:

https://www.mathworks.com/help/releases/R2024a/simulink/gui/verboseacceleratorbuilds.html?searchHighlight=accelverbosebuild&s_tid=doc_srchtitle

Additionally, to address the issue with creating the accelerator MEX file, change the mode from continuous to discrete in the Power GUI block.
