Hello，I am currently doing a simulation of a two-axis test (2D), but I am having trouble applying pressure on both sides of the two-axis (left and right). How should I set the boundary conditions of the pressure? I can’t seem to find anything on the guide.
Without specifying the PDE you are solving, there is very little chance of anyone being able to guide your.
Secondly, without providing any code, you also reduce the chance that anyone have a complete example exactly fitting your question.
