GROMACS version: 2022  
GROMACS modification: No  
I am trying to simulate a smple organic molecule (chloroethane) in water via gromacs but it appears that none of the 15 forcefiels available is working, so i resorted in making my own forcefield. how will i be able to integrate or use my own forcefield? thanks!
