The Aspen HeatX module is encountering the following problems, and I’ve been troubled by them for a long time. Does anyone know what to do? . . . :'(:'( Block: B17 Model: HEATX * WARNING HOT VAPOR FRACTION SPEC = 9.61D-01 IS MORE THAN VHIN = 1.98D-01 * WARNING INVALID HOT SIDE SPECIFICATION WITH GAINING HEAT. CALCULATION CONTINUES. One side of this heat exchanger has a hot fluid flow, while the other side has cooling water.

The vapor fraction of the hot stream feed is only 0.198; how can it be set to 0.961388? The hot stream releases heat, so its vapor fraction must be lower than that of the feed
