Numerical Modeling Workflow - Unstructured Grids



This chapter presents information on editing data in a numerical model workflow for unstructured Voronoi grids (V-Grids) and Quadtree grids (Q-Grids). The numerical models for unstructured grids are generated after you run the Conceptual to Numerical conversion step.



You must have a license of Pro or Premium in order to use the Unstructured Grid numerical workflow 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 model input files, running the MODFLOW-6 or 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 Observations

b.Define Zone Budget Zones

c.Define Particles

d.Select Run Type/Single Run



7.View Results

a.View Charts

b.View Maps
