Can I run multiple simulations on multiple cores without Parallel Computing Toolbox?

Is it possible to run multiple Simulink simulations, for example as many as there are cores in my computer, at the same time without having Parallel Computing Toolbox? I tried to do that by starting two MATLAB sessions and doing the same simulation from two different folders. Both simulations started well, but after a while the second simulation crashed.

It is not possible to run multiple simulations on multiple cores without the Parallel Computing Toolbox. In case you open different MATLAB sessions, the operating system will take care of the resources during the execution of the program, which means that it is not assured it will be on different cores. In case of complex simulations, it is more likely that the operating system will send different simulations to different cores, but it is not possible to control this from MATLAB.

Please find more information regarding running multiple simulations by running the below command in the command window of installed MATLAB R2019a version to get release specific documentation:
