Control Volume

Introduction

The control volume allows the user to define a specific region of the flow domain that serves as a “control volume,” and then compute and extract simulation data (e.g., fluid/particle properties averaged over that volume) for just that region.

Property Grid

General

Shape

Center

m | The center of the shape.

Box Lx

m | Box length in x-direction.

Box Ly

m | Box length in y-direction.

Box Lz

m | Box length in z-direction.

Cylinder

TBA

Center

m | The center of the shape.

Cylinder Axis

Vector that orients the cylinder.

Cylinder D

m | Cylinder diameter.

Cylinder L

m | Cylinder length.
