I am doing a simulation in ansys fluent involving two-phase using VOF model and I have already specified the contact angle as 3 degree, but while generating the simulation report in the place contact angle it's writing false.So what should i do for this?

Hi,

Ensure that the mesh resolution is adequate near the two-phase interface, especially at regions where the contact angle is essential. A coarse mesh may not capture the contact angle behavior accurately.

For more details on contact angle, please refer to fluent theory guide: 14.3.9. Surface Tension and Adhesion (ansys.com)

Thank you.

I have used finner mesh in the interface and as the instruction written in the 14.3.9. Surface Tension and Adhesion (ansys.com) i have used hexahedral meshes. I have selected the wall adhesion under the multiphase model and given a constant contact angle.

Please can you post screen shots of the wall panel set up? Momentum & thermal plus anything else you set.

Not the summary, the actual panel you used to set up the model.

ok i will send all the setup panel screenshot shortly
