Why i got this error and how to solve it？

I try to use ‘final states-save final operating piont’,but got the error:

" An error occurred while running the simulation and the simulation was terminated

Caused by:

• Simulink is unable to save the operating point of the C Level-2 S-Function (sfun_Controller) block '***/sfun_Controller' because the S-function has pointer work (PWork) vectors.

"

Why there are pionter vectors and how to deal with them?

Hi @katuysha,

I was facing a similiar issue when simulating my model containing S-functions. A workaround for me was to turn off the Save final operating point setting in the Data Import/Export section in the Configuration Parameters.

If saving the simulation state is necessary for your workflow, some changes can be made to the S-function to accomodate this functionality. The following documentation suggests how to achieve this using the "GetOperatingPoint" and "SetOperatingPoint" functions, along with an example:

Pwork (or Pointer work) vectors store pointers to data structures, serving as interfaces between S-functions and other applications. More information can be found in the following documentation:

Hope this helps!
