One solution would be to use tabulated potential for which the

Dear all,
Has anyone tried to use 2 van de Waals interaction types in one
system? For example, the system includes two components A and B.
The van de Waas interaction for A is LJ type, while for B
Buckingham form is used. Can GROMACS support two forms
simultaneously?
No. How would you describe the vdW interaction between an atom from
A and one from B?
If the reason for this question is based on a desire to mix two
force fields - don't.
