WebJan 31, 2007 · In sequential mode the solver solves material and energy balance equations module by module and in forward direction.So,in cases that exist recycle stream loop the user or software should select a tear stream and puts the recycle block there that is basically a mathematic algorithm like direct substitution,wegstein,newton and etc. WebThe concept of a tear stream is not used in DWSIM. In some simulators the tear stream is detected automatically, but in DWSIM you must insert a recycle block manually. The two material streams connected to the recycle and the recycle itself would then be the "tear" stream in another simulator. 28-03-17, 8:26 p.m. DanWBR Login to add comment

WebRecycle When the tear stream is determined automatically by the process simulator, it is possible to override it. For example, ASPEN PLUS selects stream S 5, but it can be replaced with stream S 6. To do so, select Convergence from the Data pull down menu. Then select Tear, which produces the Tear Streams Specifications form.
