Setting Position Information
Soil Layering (unit: cm)
You can set up to five layers. Input the depth of each border after specifying number of layers. You can change border number using the spin button. Layer number is counted from the top. n-th layer means border between n-th and n+1 th layer. Actual depth of borders are set at those of nearest element.
Space Discretization (unit: cm)
You can configure space increment (thickness of each element), z. You can set those of top and bottom. z of between top and bottom are automatically set such that those be nearly geometric sequence. Usually, small increment is set at surface zone which tends to have steep gradient. Upper limit of the number of element is 800.
For solute transfer, z should be smaller than dispersivity.
Observation Points (unit: cm)
You can set up-to eight observation points where water content, pressure head, solute concentration, and temperature are recorded. Specify the depth of each point after setting the number of observation points. Values are calculated with linear interpolation between elementまず観測点の数を設定した後,各観測点の深さを設定してください。
観測点の深さと要素の中心の深さはふつう一致しないため,線形補間で与えます。
