GROMACS version: 2020 GROMACS modification: Yes/No Here post your question : I am performing MD simulations for a protein-ligand complex. During NVT run LINCS algorithm gives an error. I have attached the error below. " Step 10, time 0.02 (ps) LINCS WARNING relative constraint deviation after LINCS: rms 104.156593, max 2735.969971 (between atoms 3316 and 3317) bonds that rotated more than 30 degrees: atom 1 atom 2 angle previous, current, constraint length 3316 3317 135.7 0.1000 273.6970 0.1000 Wrote pdb files with previous and current coordinates " Please suggest me how to resolve this.
