I build up a 1x1 squared enclosure with thermal dispersion in a porous media.
I oriented myself in the elder benchmark problem 5 “OGS-CES-I-E10 Watanabe Heat convection in a porous medium” within the book “OpenGeoSys Tutorial Basics of Heat Transport Processes in Geothermal Systems“
My model therefore, contains also liquid flow and heat transport.
I have a question concerning the boundary conditions and material parameters.
The benchmark problem has on the TOP a constant Temperature of 0°C and on the BOTTOM_HALF_RIGHT a constant Temperature of 1 °C.
They use in the BC file also the unit °C but all the other parameters in the other files are given in Kelvin.
So, my question is: Is it possible to do that?
I tried to change the BC into Kelvin but then I get unreasonable results. When I changed it back everything is fine.
My model based on the benchmark problem, so I get the same problem concerning the units in the BC file
If I use Celsius in the BC file and all the other parameters in Kelvin the results looks fine but by changing the values in Kelvin I get a rejected time steps.
I hope you can help me.
PS: Sorry, for my msp file. It couldn’t be upload in the original shape.
