Model #1878

Hi:

Can anyone help me to take a look at the model named Filling of a Capillary Channel. The boundary condition for boundary 8 is setting the P0 to be an expression: rho_twophase*z*gz_twophase. What exactly the meaning of the rho_twophase and gz_twophase, looks like two build-in variable The strange thing is that when you type this line into a new model you set up following the step-by-step instruction, the system always inform you inconsistant unit. I don't know how this comes. Anyway, I set the p0 to be rho(T_ref[1/K])[kg/m^3]*z*g as I understand, but after the reinitiation, the solver returned the error message and say unable to evaluate the function rho.

Thank you for your advice.

Peng

rho_twophase is density, and gz_twophase is gravity force, I think.
