Limitations

Sol2SPH is not compatible with SPHBCS and inlet/outlet options.

All SPH and Sol2SPH parts should have the same pitch.

As Sol2SPH particle configuration is cubic, SPH parts should be also use a cubic net.

Using /DT/BRICK/DEL is the most CPU efficient way of using Sol2SPH.

The minimum time step should be around 20-30% less than the natural time step.

It is recommended to use nodal time step for better SPH particles stability.

After the deletion of a brick, the time step may be as low as:(1)

Δ t = \frac{Δ T_{min}}{N d i r}

$Δ t = \frac{Δ T_{\min}}{N d i r}$

Where,

$Δ T_{min}$ $Δ T_{\min}$: Deletion brick time step as defined in /DT/BRICK/DEL
$N d i r$ $N d i r$: Number of created particle per direction
