Why does MATLAB crash when simulating a generated FMU in Simulink Compiler?

16 views (last 30 days)
When I created a FMU file by Simulink Compiler and run it on my Simulink model, MATLAB crashed without any error messages and log files.

This behavior occurs in the case that you haven't installed supported compilers in R2020a and later release.
In this case, build-in compiler LCC-win64 is used for creating a FMU.
However, the purpose for LCC compiler is to aid inhouse products such as Stateflow and MATLAB Function Block simulate, so that we don't recommend to use it for other applications (Sfunctions, MEX files, FMUs, accelerators, SIL/PIL).
To work around the issue, please install one of supported C Compilers like MinGW. 
For all supported compilers, see https://www.mathworks.com/support/requirements/supported-compilers.html
Note: If you use Simulink Coder, you can verify the compiler used for code generation:
In the Configuration Parameters window(Ctrl+E), you can go to Code Generation -> Build process -> Toolchain Settings -> Toolchain Or  In the MATLAB Command prompt(commandline): get_param('modelname', 'Toolchain')

User can verify the compiler used for code generation:
in UI, they can go to Model Settings->Code Generation ->Toolchain Settings -> Toolchain
or commandline: get_param('modelname', 'Toolchain')
For all supported compiler, see https://www.mathworks.com/support/requirements/supported-compilers.html
