How to use the operators-' env and bndenv '?

The operators ‘env and bndenv’ are available for the Particle Tracing Module. However, I have no idea how to use them, even if I read the user’s guide description as below:
Evaluating env(expr) on a particle, evaluates expr at the point in the domain where the particle is. When evaluating a variable var on a particle, if the variable is not defined on the particle it is automatically replaced by env(var). Therefore the env operator can often be omitted.
Evaluating bndenv(expr) on a particle, evaluates expr at the point on the boundary where the particle is. If the particle is not on a boundary, the evaluation fails. Use this operator instead of env when evaluating expressions that are only defined on boundaries.
Does anyone take a example to use the operators?
I would be pleasure if anyone respond the problem.
