The tear‐stream method is necessary because it “breaks” this loop: you select one recycle stream as the tear, assign it an initial guess, and then solve the rest of the flowsheet as if it were acyclic. Once the downstream units compute their outputs, you compare the calculated value of the torn stream to your initial guess and iteratively adjust until they coincide. Without tearing, the solver cannot establish a proper topological sequence or drive the recycle to convergence, making initialization—and ultimately steady‐state convergence—impossible.\n", "\n", - "![](HDA_flowsheet.png) \n" + "It is important to determine the tear stream for a flowsheet which will be demonstrated below.\n", + "\n", + "\n", + "![](HDA_flowsheet.png)\n", + "\n", + "Currently, there are two methods of initializing a full flowsheet: using the sequential decomposition tool, or manually propagating through the flowsheet.
