How to set gravity in porous media "thm_example"? #17015
-
Hi Currently the example (modules/porous_flow/examples/thm_example/2D.i) does not consider gravity. I have attempted to set it by setting "gravity = '0 -9.8 0'. However, it seems the gravity effect does not appear--there is no difference in fluid saturation whether I set gravity on or off. I expect the gas phase would move to upper regions. How can I correct this? Thank you! Modified file with following modifications: [Mesh] [GlobalParams] |

Oh, it is just due to I did not notice the setting of permeability field in the original 1D problem. permeability = '2e-12 0 0 0 0 0 0 0 0' |
