How to mesh between two surfaces

Hello,

I am trying to mesh a model that is a cube into another cube. I want to mesh the volume between the two of them with tetras, but i cannot. I am using volume tetra, with enclosed volume: surfs. I only can select one of the two surfaces. Could you help me?

Thank you very much for your help.

MY ANSWER IS YES, IF YOUR MODEL IS SYMMETRIC ABOUT THE AXIS.

AS OF MY UNDERSTANDING CONNECT ANY ONE OR ALL THE FOUR EDGES OF THE EXTERNAL CUBE WITH THE INNER ONE BY SURFACES (USE RULE OPTION)

NOW TRY IT ONCE, IT WILL WORK OUT

Thank you for your help raviteja, my model is not symmetric, the internal surfaces is an offset of the external surface

I create a surface with the ruled option that connects the two volumes, but when i mesh with tretramesh (volume tetra with enclosed volume: surfaces). The program start the mesh, but then it says 'Volume analysis failed'. Do you know what happens?

Thank you very much
