Block Model Import

When a file with the extension .bmf is selected, the algorithm detects that it contains a block model.

• In the File Information section, you will have an overview of the contents such as the type of content (here: Block Model) and the origin, extension and orientation of the block model. The geometry of the cells is given by Base grid schema (block size of the base regular grid) and Sub-blocks schema (minimum and maximum ranges for the sub-block sizes). The number of blocks (block count) is given too.

• All the variables defined on the block model support are listed in the following section. By default, all the variables will be imported (the checkbox Import All Variables is ticked). However, you can individually select the variables you want to import by unticking Import All Variables and only tick the required variables. These variables will be imported directly with the block model and will be available in the data tree, when you click on the block model.

  The "All Variables" checkbox needs to be used in Batch Recording to export all the variables, even if they change for each run of the Batch file (useful to import multiple files with different variables, within the same Batch file).

  Note: Vulcan numerical variables are imported as numerical variables and Vulcan string variables are imported as categorical variables.

• Output: Enter the name of the file that will be created in Isatis.neo data tree. By default, the name for the output file is the same than the name of the Vulcan file (without the extension).

  Note: The Vulcan block model is imported in Isatis.neo as a Regular grid in case of regular geometry, or as a Sub-block model to fit an irregular geometry.

• Create Parent Regular Grid: This is optional. This section only appears in case of irregular grid. When a block model file is imported as a sub-block file, this option allows to create a regular grid with the geometry of the parent grid, at once. The regular grid will be created in the same folder as the sub-block file in the data tree of Isatis.neo.

  • Parent Grid Name: Name the parent grid. By default (using the magic wand) this is the name of the points file, with the suffix “-parent”. You can also use the pattern "%file" and the parent grid name will use the associated sub-block file name.
  • Store variable statistics in parent grid: The resulting regular grid file will contain statistics of the variables defined on the original sub-block file. For numerical variables, each parent cell will contain the mean value calculated from all the sub-blocks in the parent cell, weighted by the volume of each sub-block. For categorical variables, the parent cell will contain the proportion of volume in each category.
• Display: Select the toggle to display in a defined scene (2D or 3D) a new layer displaying the imported data. The cells of the (sub-)block model will be colored according to the first non-structural numerical or categorical variable.
