Hi,
I am currently making a 3D model that includes a basement of a building in the overall model area. I need to have the walls of the building finely discretized so they have 3 layers of elements within 0.5m, but only to a depth of 3m (the depth the building’s basement). However, the depth of my model needs to be at least 130m (I will be adding BHEs eventually), and having such high discretization all the way down to 130m generates far too many nodes and elements which is too much for my system to handle.
I am wondering if there is a way to selectively discretize only the layers or slices that make up the top 3m of the model, leaving the lower layers with fewer elements/nodes. I do have a shapefile for the walls themselves (as well as the interior of the building, excluding the width of the walls), if that helps in any way. I did see previous posts that suggested using TetGen for re-meshing around points, however I’m not sure that would apply to my issue.
Thanks in advance,
Ronan
