Hello everyone,
I'm using the UDS for my equation, which is make up of three terms： unsteady term and diffusity term on LHS while the explicit term on RHS. And its TEX can be written as :
$$ \frac{1}{c^2}\frac{\partial^2 p}{\partial t^2} - \nabla^2 p =0 $$
In two domains, there is one pair of interface connected with each other. Actually, the two domain is one-domain, which is separeted by ME with the aim to check the correct behaviour of UDS boundary condition.
