Other Modeling Guidelines
Limitations
Sol2SPH is not compatible with SPHBCS and inlet/outlet options.
Mesh Sizes and Other SPH Parts
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.
/BRICK/DT/DEL
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)
Where,
- Deletion brick time step as defined in /DT/BRICK/DEL
- Number of created particle per direction
