If you're using Obi 6.X, you can't just access the solverIndices array directly using contact.bodyA.

contact.bodyA is a simplex index, not a particle index. You need to get the particle index out of that simplex. See the manual for examples on how it's done:
http://obi.virtualmethodstudio.com/tutor...sions.html

For instance:

Code:

// retrieve the offset and size of the simplex in the solver.simplices array:
int simplexStart = solver.simplexCounts.GetSimplexStartAndSize(contact.bodyA, out int simplexSize);

// starting at simplexStart, iterate over all particles in the simplex:
for (int i = 0; i < simplexSize; ++i)
{
    int particleIndex = solver.simplices[simplexStart + i]];

    // do something with each particle, for instance get its position:
    var position = solver.positions[particleIndex];
}
