Hi people!

I'm tring to generate volume mesh in my pipe model , the surface mesh it's ok , but when I start the volume ones , volume meshing end with this error:

Error: Invalid connectivity in Regions Fluid and Solid
{Command=GenerateVolumeMesh, command=CommandComplete, Processor=0, In=[Machine::main, VolumeMeshingModel::execute], CompletedCommand=GenerateVolumeMesh}

I've have no idea what kind of error is , becouse I think the model is ok : I have 2 regions ,a solid(heat shield) and fluid one and i used contact interfaces beetwen them. The surface diagnostic doesn't give me any error!
I noticed that after surface mesh ,all the interfaces boundaries of both regions have a faces number equal to zero and the relative icons are darken .

Maybe the error dipends of this? What can I do?

Anyone can help me?

Thank you people!
