Hi

Could someone help me to define boundary conditions of my model.

As you can see in attached picture, I used multi grid in my model and I want to know what I should choose for boundary conditions in X and Y directions for finer mesh.

thanks

FLOW-3D will change all boundary conditions of the finer mesh automaticaly to 'internal', because you used a nested mesh setup. That means, you do not have to apply any special boundary condition to the finer mesh.

Thanks for your reply

Do you mean that I should choose Symmetry for all of boundary conditions?

Independent from what you have choosen, FLOW-3D will change the boundary condition of a nested block to 'internal'.
