Hi All,
I am modeling BHE with FEFLOW7.5 and wondering where to define the density of solid phase? I checked the documentation and only found density for fluid and refrigerant.
Thanks in advance,
Haiyan

The density values are implicitly given through the volumetric heat capacity rho_s * c_s. Specific heat capacity has units of J⋅kg[sup]−1[/sup]⋅K[sup]−1[/sup]. The FEFLOW parameter is in J m-3 K-1. The factor is exactly the density (kg/m3).
Cheers
Carlos

Thanks, Carlos.
But I only find the volumetric heat capacity under the 'material properties'. Where is the specific heat capacity defined?
