Hello everyone,

I ran Benchmark 5.2 (Borehole Heat Exchangers: Comparison to Sandbox Experiment) from the book “Geoenergy Modeling II Shallow Geothermal Systems” using ogs5py but showed below error in the output.

ValueError: C: \ ogspy5 \ project \ beier \ beier.mmp: Unknown sub-key:BOREHOLE_HEAT_EXCHANGER

I also ran this example directly in ogs.exe version 5.8, but it closed as soon as I run the program.

Can someone help me how to solve this error?

Thanks in advance
