    So I'm using the Grid Overlay with Keq method and have 4 materials in my solid. Each one has a different Kh and a Kv set at 1/10 of the Kh. Based on my understanding of the method and the help description ("Rather than simply assigning materials based on which solid encompasses the cell centers, the Keq method attempts to compute a custom Kh and Kv value for each cell. When assigning the material properties to a cell, GMS computes the volume of each solid in the cell and computes an equivalent Kh, Kv, and storage coefficient for the cell that takes each of the solids in the cell into account. Thus, the effect of a thin seam in a cell would be included in the Kh and Kv values for the cell."), I would expect to see my resulting Kv for each cell be 1/10 of the Kh computed. I am finding that the calculated value is often much lower than the expected value. Does anyone have insight on this matter?

    Right, but it is the combination that I think is incorrect for Kv. Let's say I have 2 materials being combined in a cell. Material 1 has a Kh of 100 ft/day and a Kv of 10 ft/day. Material 2 has a Kh of 10 ft/day and a Kv of 1 ft/day. If the volume of each material in the cell is 50% of the cell, I would expect the resulting Kh to be 55 ft/day and the Kv to be 5.5 ft/day. Kv is 1/10 of Kh. However, in reality, I'm getting results for Kv which are much smaller than 1/10. This is why I'm questioning it.

    The combination of multiple materials in a newly created cell will result in a representative conductivity value. That is, I think you're seeing a combination of materials instead of a cell containing only a single material.
