  1. Porosity 100 m .15 .325 .5 100 m

  2. Field variables are constant in space (homogeneous) by default. Click + to expand, then to select options. Porosity is 30% throughout the domain.

  3. Random field Porosity varies about a mean of 30% with a standard deviation of 5%.

  4. Supply values node-by-node from a table dataset. Read in values from .txt file. Click Browse…

  5. Enter values into a node-by-node editor. Click Edit… Nxcolumns Type or paste values for each nodal block into an editor. Nyrows

  6. Type in a simple expression. Porosity varies periodically over the domain according to a trigonometric function.

  7. Type the BASIC script into an editor Click Edit… Porosity on the left half of the domain is 30%, and on the right half is 20%.

  8. Prepare a script in the BASIC language, save as a .bas file. Click Browse… .bas script file Porosity is 50% in the center of the domain, 25% everywhere else.

  9. Write and compile a C++ function for maximum flexibility Click Browse…

  10. Your function for field variables can utilize internal parameters and syntax listed in theGWB Reaction Modeling Guide (RMG) and the GWB Reactive Transport Modeling Guide (RTMG). For details, see “Custom Rate Laws” in the GWBReaction Modeling Guide and “Heterogeneity” in the GWB Reactive Transport Modeling Guide.

  11. Porosity has been set as a random variable.
