Hi, I apologize if this has been asked before--I couldn't find it in the archives.
Here is my situation: I have a model (an earth model) that is a box. But inside the box I have layers that represent earth layers. The boundaries of these layers are defined by a set of x,y,z coordinates. This seems like a fairly common starting point for building a mesh, but I don't quite follow from the instructions how to do this. It seems that I need to mesh before I mesh, creating a 2-D mesh of the nodes that define my layer boundary in order to define facets and surface loops. Is this right? Or is there a way to say, "I want this collection of nodes to represent the top boundary of this volume"? Thanks for the help, --Jack
