Dear All,

I’m wondering is there a way to assemble the discretized BIOs associated to Stokes equation? I looked up the documentations and it seems there are interfaces only for BIOs of Laplace, Helmholtz and Maxwell equations.

Thank you!

The BEMPP library currently does not provide functionality for the Stokes equation. Implementing BIE for Stokes flow requires programming the calculation of Green’s functions (fundamental solutions) for the Stokes equation in the core of the library.

Thank you for your kind reply. Is there any plan of adding the Stokes BIO to BEMPP in the future? It seems not so difficult in term of the form of the Greens function but very useful. It would also be great if BEMPP can provide some customized op interface!
