Immersed Boundary Method (IBM)

[MWTWM M]

Dear community,

 

Within a numerical simulation framework based on the Immersed Boundary Method (IBM), is it feasible to explicitly model solid regions using the userf subroutine in order to simulate rough walls or particle-laden flows? If feasible, would this approach reduce the solution accuracy near the wall boundary? Moreover, does such an implementation inevitably introduce empirical models or parameters?

Any suggestions and criticisms are appreciated.
