Hi!Well, I used it a couple of times to do debug some force analysis. It could also be useful for doing off-line analysis of forces, if you want also the random forces to be included. And finally, the testsuite currently relies on it for reading back the expected forces.
On the other hand, is there a good reason not to be able to set the forces? The forces don't influence the integration and get overwritten, but for analysis they still play a role, see the testsuite.

We have just wondered why ESPResSo allows you to *set* the force on a particle, like part 1 f 1 2 3 Once you do integrate 0, the force is overwritten. We know that being able to write f allows the force to be restored from a blockfile, but is there any other reason? Does it make any actual sense that the force in a particle is writable?
