ERROR: Error with GENERAL_MODE phase boundary condition: Missing dof.

[Bisesh Joshi]

Hi all,

I'm using general mode and assigning the following flow conditions. However, I'm getting this error: ERROR: Error with GENERAL_MODE phase boundary condition: Missing dof.

Please let me know if you have any idea. Thank you so much in advance.

Best regards,

Bisesh

Bisesh,

I suspect it is the “recharge” (I prefer MASS_RATE over VOLUMETRIC_RATE for multiphase) or “top_pressure” flow condition. Try commenting out each individually to narrow down which is causing the error.
