The Disposer block disposes of entities after they are no longer needed in the model, reducing memory usage. For optimal memory management, you should route entities that are no longer needed to a Disposer block. It is possible to have more than one Disposer block in a model. The disposer block keeps a count of the number of entities that enter the block. If there are connections to the block’s OutCount port, the count is pushed out the port every time its value changes.
