Hello I am trying to add van-der-waal force to the list of particle forces in a copy of lagrangian/intermediate/submodel/kinematic/particleForces directory on OpenFoam version 6. I have written the code attached below.

In the code I try to create an array of Lagrangian parcels/particles, but I do not know the right class to declare the array so I am having problems doing it. Could someone please guide me on how to do this.

Also if you have time to notice any other problem, please tell me. Thank you.
