Index of Anisotropy

Use this command to specify the index representing hydraulic anisotropy tensor, KA, in three-dimensional applications. The actual components of the anisotropy tensor are entered in the Tensors of Anisotropy dialog window. The anisotropy tensor for three-dimensional applications is defined by three principal components, K1A (ConAX), K2A (ConAY), and K3A (ConAZ), and six coefficients aij that represent the cosine of angles between the ith principal direction of the tensor KA and the j-axis of the global coordinate system (i.e., cos(X-x), cos(Y-y), cos(Z-z), cos(X-y), cos(X-z), cos(Y-z)).
