The Weights window contains the list of weights assigned to each data point that is used to generate a predicted value at the location marked by the crosshair. Weights assigned to data points are illustrated in the following example: Search Neighborhood illustration It gives greater weights to points closest to the prediction location, and the weights diminish as a function of distance, hence the name inverse distance weighted.
IDW assumes that each measured point has a local influence that diminishes with distance.
The measured values closest to the prediction location have more influence on the predicted value than those farther away. To predict a value for any unmeasured location, IDW uses the measured values surrounding the prediction location. Inverse distance weighted (IDW) interpolation explicitly makes the assumption that things that are close to one another are more alike than those that are farther apart. The results show that the proposed transformation technique and its corresponding interface program transformed the SURPAC model into the FLAC3D model, which expedited FLAC3D modeling, verified the validity and feasibility of the transformation technique, and expanded the application spaces of FLAC3D and SURPAC.Available with Geostatistical Analyst license. Then, the interface program that transforms the mine design model to calculate the model was compiled using FORTRAN, and the specific steps of the program implementation were described using a large iron and copper mine modeling example.
First, the relationship between the FLAC3D and the SURPAC unit data was examined, and the transformation technique between the data was given. Abstract : Given that FLAC3D (a geotechnical calculation software) is difficult to use for building large, complex, and three-dimensional mining models, the current study proposes a fast and a convenient modeling technique that combines the unique advantages of FLAC3D in numerical calculation and those of SURPAC (a mine design software) in three-dimensional modeling, and the interface program was compiled.
