Which SPH packages do you recommend?
 

I am currently diving into the sea of open-source project for SPH flow simulation. The two candidates I have come across are DualSPHysics and LAMMPS. Both are open-source and have a certain degree of user-modifiable codes. However, I wonder as I go along with my project (I have only spent a couple of hours playing with each of them), which one will be easier for me to handle? In terms of robustness and code sharing (for reproducibility in the future.)

People who have experience with both packages, may I ask for some insight views?
