Error with s-function when simulink system is called within a matlab function

I face a problem regarding the simulation of a Simulink file. In my main file I am calling a function and within this function I am using the sim command
sim('Simulink_file_name', 'SrcWorkspace', 'current');
to run the simulation. For the simulink to have access in the caller workspace, I have to use the SrcWorkspace argument. However, the simulink file seems to be unable to read the s-functions which are needed. The error that I get is the following.
Error using 'Simulink_file_name'. Error in 'Block_name' while executing C MEX S-function 'S-function name', (mdlStart), at time 0.0. Caused by:
Error using Simulink_file_name
Could not get the variable 1.
Of course, when I try to simulate the system in my main loop instead of a function, everything works properly.
Has anybody experienced a similar problem or knows how I can circumvent it?

You need to specify the srcworkspace as 'Parent'.
