Do you use SPH (Smoothed Particle Hydrodynamics) or grid-based methods for most of your CFD simulations?

I prefer grid-based methods

in order to deliver realistic projects and complex models we use PowerFLOW EXA software which is Lattice Boltzmann application based on Particles discretization.

the software use the LBM and allow accurate results independently from the user and mesh. the software is used by all the automotive companies due its speed ,  accuracy and repeatability

for more information please let me know and I will be able to guide you towards the best usage in CFD especially in universities cases and real projects 

yes, I have used grid based method and I have used gambit.

Whats the meaning of SPH n why it is used
