    Hello,
    I would like to simulate a multi-component flow through a porous structure. To do this, I need the contact angle. I saw in the gasStorage2d example that it is possible to integrate the contact angle using the PhaseField method. Is this also possible with the pseudopotential ShanChen method? Unfortunately, I couldn’t find any information on this.

    I would be very grateful for any help!

    Hello,

    it is possible in a very similar way using the geometric contact angle boundary condition by assigning the right density to solid boundary nodes using a geometric rule just like the model in gasStorage2d.

    Kind regards
    Tim

    Thank you!

    What is the name of the boundary condition I have to assign to the solid nodes? Unfortunately I couldn’t find it in the shan chen documentation.
