sph paticles in ABAQUS

[MOHAMMAD TALAL]

I deformed a fluid as sph particles but I have a problem with how can add pressure or velocity from boundary conditions.

other things, when I made very long fluid that will transfer to the particles the job of software stop to work and give error 11. could I make an infinite number of particles in abaqus??

 

[FEA way]

Check the documentation chapter "Smoothed particle hydrodynamics", which describes boundary conditions in this type of analysis, among the others.

The number of particles can’t be infinite, just as it is with other types of elements. However, you can use a particle generator feature that will keep adding new particles throughout the analysis.

When it comes to the error that you get, more details will be needed to help. Maybe there are some additional, more specific error messages in output files.

how can I make particle generator feature in ABAQUS

 

[FEA way]

It has to be defined using keywords. The basic one is *Particle generator and then there are some additional keywords for further setup. This functionality is the same as particle generator used with discrete element method, which has its own chapter in the documentation.
