Christian Jakob proposed the following answer:
> None of them don't affect the movement of particles.

Did you play with suction parameter in the script I send you?

It definitely changes the forces and rupture distance, just check it
out.

> In addition, I have also changed the particle distant and it did not
work.

In your script aabbs are exactly touching, if particles are touching. So
you need to enlarge aabb in this case:

"In order to allow capillary forces between distant spheres, it is necessary to enlarge the bounding boxes using Bo1_Sphere_Aabb::aabbEnlargeFactor and make the Ig2 define define distant interactions via interactionDetectionFactor. It is also necessary to disable interactions removal by the constitutive law (Law2). "
