Hi, im doing a counterflow heat exchanger on fluent, and ive been following these tutorials:
https://www.youtube.com/watch?v=BEzhDIR_zOY https://www.youtube.com/watch?v=ab5s2cAw8XQ to aid my simulations. The simulations are using the patch function to assign temperatures to certain zones, but when i use the patch function it seems to apply the temperature to all the zones. Does anyone know a way i can get around this? Or should i just use the fixed values within the cell zone conditions tab? Thanks |

The patch function applies the patch to whichever zone you select and all zones if you do not select any zones.
If this is too global, you can mark regions and then patch those regions. The patch option overwrites the current solution value with whatever the patch value is. On the next iteration the values will be updated with the new solution values. The fixed value option in cell zone conditions, overwrites and holds the values. The values will never change. It is very different than the patching. |
