Apply boundary condition in sph(smoothe particle hydrodynamic) method
 

Hi.
I'm simulating lid driven cavity problem by sph method, but I don't know how can I applying ghost or dummy boundary for simulating lid of cavity.
Please help and thank you very much in advance.

Apply Dummy particle
 

To apply dummy boundary, U need to read the code in SPH book for Liu,
First u need to add the dummy boundary for initialinput file,
Now I am studing about ghost particle
I want to implement it explicity, So please if u found answe about ghost particle, Please let me know
