Cannot allocate sufficient memory for log variable

Hi, guys!

I'm running a pretty long simulation in Simulink and in the end of it I have to save some variables. I am using the block to workspace, but before get anything saved I have the following error:

Data logging exceeded available memory

Cannot allocate sufficient memory for log variable. Consider disabling logging or reducing the length of the simulation.

Does anyone know how to deal with it? Is there a way to divide the data into two different variables in Simulink to avoid this situation?

Thanks!

The problem is not with any one variable getting too large: the problem is with the total size getting too large. You are logging to memory, and running out of available memory between the total of everything that is getting logged.

You can be more selective about what you log. For example perhaps you could use a Rate Transition https://www.mathworks.com/help/simulink/slref/ratetransition.html to sample a signal.
