Numerical Modeling Workflow - Unstructured Grids


This chapter presents information on editing data in a numerical model workflow; the numerical model for MODFLOW-USG is generated after you run the Conceptual to Numerical conversion step.



You must have a license of Pro or Premium in order to use MODFLOW-USG in Visual MODFLOW Flex.



The numerical modeling workflow provides the tools for defining, viewing and editing the numerical model (properties and boundaries assigned to grid cells), creating the input files for MODFLOW-USG, running the MODFLOW-USG engine, and analyzing the results. The following sections are covered:



1.Define Modeling Objectives

2.Define Properties
(edit parameter values, display in plan, XS, and 3D views)

3.Define Boundary Conditions
(constant heads, drains, pumping wells, recharge, etc.)

4.Select Next Step

a.Define Observation Wells

b.Define Zone Budget Zones

c.Define Particles

d.Select Run Type/Single Run



7.View Results
