Disabling regridding for some cases via input file

1

One way could be to use ``` REGRID_CFL_INTERVAL = 5e7 // Some large value for IB simulations as parent integrator or REGRID_INTERVAL = 500000000 // Some large number for Navier-Stokes/Adv-diff...

Convergence of subdomain solvers on level 0

25

Has anyone looked into non-convergence of pressure solvers on level 0? They don’t converge with single-phase (`HypreLevelSolver`) and multiphase (`PETScLevelSolver`) flow solvers.

Make SpongeLayerFunction class general

1

This line of code is limiting the usage for multiphase flow apps. https://github.com/IBAMR/IBAMR/blob/master/src/navier_stokes/SpongeLayerForceFunction.cpp#L133 We can provide a user input parameter `chi` instead of `rho` and make it more flexible.

Error during make

### Discussed in https://github.com/libMesh/libmesh/discussions/3356 Originally posted by **amneetb** July 29, 2022 Hi all, I am getting the following error during the make stage of libmesh v1.7.1 ``` In file included...

@abarret : rebasing #1630, #1631 and #1633 against master was a mess (tons of merge conflicts). I cherry-picked the commits from these three PRs and played it on top of...

Specifying P_problem_coef in StaggeredStokesOperator class

12

Currently we have `setVelocityPoissonSpecifications()` routine in StaggeredStokesOperator class to specify U problem coefficients; see https://github.com/IBAMR/IBAMR/blob/master/include/ibamr/StaggeredStokesOperator.h#L99 For acoustic streaming flows, we compute $\nabla \cdot (\mathcal{D} \vec{u})$ as the low Mach equation...

P_problem_coef objects

5

We use `D_coef` from d_P_problem_coefs PoissonSpecification object in StaggeredStokesProjectionPreconditioner; see https://github.com/IBAMR/IBAMR/blob/master/src/navier_stokes/StaggeredStokesProjectionPreconditioner.cpp#L299 When we register PoissonSpecifications object with StaggeredStokesProjectionPreconditioner, it is synchronized with the pressure solver PoissonSpecifications object; see https://github.com/IBAMR/IBAMR/blob/master/src/navier_stokes/StaggeredStokesBlockPreconditioner.cpp#L116 I...
