The extension of the immersed-boundary forces from the moving grid to the fixed fluid grid and the restriction of the fluid velocities from the fixed fluid grid to the moving grid have been modified to be second-order accurate.
The accuracy of the procedure is depending on the fluid grid resolution, but independent of the solid loading.
Since classical solid/fluid coupling algorithms rasterize the solid body onto the fluid grid, an entirely new approach is required to treat thin objects that do not contain an interior region.
The fluid particle interaction is studied using a new procedure called the offset method, which results in several numbers of spatial displacements of the fluid grid.
The proposed procedure allows the variation of the fluid grid resolution independent of the particle size and consequently improves the calculation accuracy.
An efficient algorithm is presented which distributes the Lagrangian markers non-uniformly to match the fluid grid and keep the number of markers optimized.

To overcome frequency bandwidth limitations associated with coarse resolution fluid grids, we simulate micro-bubbles in the audio domain using a power-law model of bubble populations.
The proposed procedures, especially the projection of the exact Riemann solutions onto the fluid grids, are designed to be simple and consistent in any spatial dimensions.
We also simulate the dynamics of a vesicle traveling through a narrow channel and observe the ability of the lubricated method to capture the vesicle motion on relatively coarse fluid grids.
Two types of coarse graining enter into consideration: coarse fluid grids as well as particle coarsening in the form of parcel-based simulations where only a subset of particles is simulated.
Dreamweaver, too, is getting support for these web fonts and now features an updated grid layout for creating fluid grids.

Since I tried Ludwig back in 2017, I have been constantly using it in both editing and translation. Ever since, I suggest it to my translators at ProSciEditing.
