TEXT(Batch Reactor - super wafers :D108 TITLE DISPLAY This q1 file simulates an batch chemical vapour deposition reactor as shown below; the reactor is axisymmetric and contains four super wafers on the axis. It is a test case developed to indicate the use of super wafers. This case should be looked at in combination with liibrary case D107. Laminar, steady-state flow is assumed.
