Hy!

I work on a 2D combined heat/flow problem.

I use time varying Flux boundary condition [J/d] as geothermal output/ input rate.  I further more use constraint conditions (constant) min: 0°C; max: 25°C on the same knots.

The temperature hydrograph looks fine (temperature never drops below 0°C). But the Budget Analyzer puts out way to large influx and outflux  ???

Can someone help me on this problem? How does FEFLOW work with constraint condition, when the boundary condition is much to high for the constraints?

Thanks a lot
