| This block can be a very helpful tool for testing models that contain a big number of [[Compartment|compartments]]. When the user wants to make sure that compartments inventory is not going bellow the 0 value, the "non-negative" field is selected inside the compartment. This is a useful feature of Ecolego, however, if the user is not careful, they can create systems that might have some "false positive input" (where the inventory of one compartment increases, even though it should decrease). When using this mentioned feature, it is important to write proper logical equations inside the [[Transfer|transfer]] blocks connected to these compartments, to take into account of this truncations. To make sure this is done properly, one might want to use the Mass balance block. This block can easily detect if there are any discrepancies of this sort, and show the difference from the excepted output and the actual output of the model. | This block can be a very helpful tool for testing models that contain a big number of [[Compartment|compartments]] and are using the "non-negative" option.
