Hi everyone,

I have started learning gmsh and kinda got stuck at one command.

I try to create multiple layers on a particular surface using the command

Layers { { expression-list }, { expression-list } }

Can someone tell me how exactly should the expression list in the sceond bracket be specified. What does it mean exactly?

The code below is taken from a tutorial case, if someone can please explain what those 0.5 and 1 mean and how to define them, it would be great

Extrude {0,0,h} {
  Surface{6}; Layers{ {8,2}, {0.5,1} };
}

Thanks once again as always!!!!
