refine the grid around a containment wall

[Lalith]

Hi All,

I have to include a containment wall into an existing mudflow model in GMS. The grid is coarse around this wall. The wall is available as a GIS shapefile (line feature object). My model has 9 layers but the wall runs from the surface to halfway of the 3rd layer. I have 2 questions

1. How do I refine the grid around the containment wall (shapefile or line feature object)?

2. Should I split the 3rd layer at the bottom elevation of the wall, give the properties of the existing 3rd layer to both of these new layers as a result of splitting (say 3rd upper and 3rd lower) and define the wall from the surface to the bottom of the 3rd upper layer? or is there any other way to do this in GMS?

I very much appreciate all your responses and suggestions.

Thank you,

Lalith

To refine the model around the contaminant wall you would follow the same process used to refine around observation points in this previous post:

As far as determining if the 3rd layer should be refined, it's hard to say. It might be good to try it both ways and see the difference.

Thank you Bill,

I was initially wondering if GMS recognizes lines for refinement. I did them using several points. I was also able to split the layer in the middle but was not able to split at a provided ratio of thickness.
