If I know the heat flux (18 W/m^2), should I use the Neumann boundary condition?
can I use it in TOUGH2?
You can enter it in the GENER block, as heat sink source (check the users Guide). You enter J/s for a grid block. You just have to make sure you apply it correctly.
Thank you Yingqi,
1 watt/meter² [W/m²] = 1 joule/second/meter² [J/(s·m²)]
That means I can convert it to J/s based on the cell cross-section area, correct ?
Yingqi Zhang Thanks
