Thanks for mentionning that. A bug had been introduced (I don't know when/who) in some type checking and the solid volume was wrong (hence the void volume was negative). It is fixed in r2977.

For choosing the parameters, it is up to you to define what you want to simulate.

Can you help with this problem?
