 ====== Commit 2018-09-20 ======
+===== Description =====
+To try to model an additive manufacturing process I first tried to use Metafor as is. The activation of the elements over time can be done by using the StageManager and by activating/deactivating interactions at predetermined times. Like this, I managed to reproduce with accuracy the results of a test case from the literature. This method is however very tedious to use and requires to create an absurd number of interactions. It is also not CPU efficient. I had to implement the Verbose option for StageManager because of the very high number of text at every activation/deactivation of elements, which in my case took more time than the actual test cases.
+One can realize that the previous method of activating/deactivating elements is not efficient enough and a new method has to be implemented. I thus implemented a new class called AdditiveManager that will manage the activation of elements in a more efficient way.

 ==== AM tests using AdditiveManager: ====
-"withAdditiveManager/battery/activationWithAdditiveManager.py" is a test with the activation of 1 simple line of elements (and no boundary conditions) using AdditiveManager, it is used to compare with "withStageManager/battery/activationWithStages.py". They correctly give the same resultsas shown here under (temperature at a point over time).

They correctly give the same results as shown here under (temperature at a point over time). Even for such a small test case, there is a **30% decrease of the computation time(30->20s)**.
