complex boundaries

[zzzaaalll]

Hello everyone,

I'm writing to you to ask if the last version of Espresso provides for the possibility of inserting boundaries of arbitrary shape? Actually a few years ago I obtained this result in the publication reported in the link below by inserting a mesh kept fixed during the simulation (the green mesh in fig. 4). However, the drawback of this method is that the resulting boundaries didn't behave correctly with the Lattice-Boltzmann fluid (the flow lines crossed the boundaries).

Thank you in advance for your support.

Best regards

G
