# What is a domain in Ansys?

Contents

A Computational Fluid Dynamics (CFD) domain is the portion of space where the solution of the CFD simulation is calculated. … Meanwhile, in internal flows, the computational domain is defined by the confines of the geometry itself and the space inside the geometry is discretised into a computational grid.

## What is a computational domain?

The computational domain refers to a simplified form of the physical domain both in terms of geometrical representation and boundary condition imposition. This simplified form should retain all physically important features of the problem but can ignore minor details.

## What is a flow domain?

The flow domain is the volume in which the flow takes place (a 2D model assumes a unit depth into the screen). You don’t have to draw a smaller volume for the flow. The walls (faces) of the brick (volume) are the boundaries of the flow domain.

## What is fluent domain?

domain is passed by ANSYS FLUENT and is the pointer to the domain structure. You supply the integer value of zone_ID. … First, you will need to get the integer ID of the zone by visiting the boundary condition dialog box (e.g., Fluid) and noting the zone ID.

## What does meshing mean in Ansys?

Meshing is the process of turning irregular shapes into more recognizable volumes called “elements.” Before you start meshing, you must first upload a geometry or CAD model into, for example, Ansys Mechanical to begin the simulation process.

## What is a physical domain?

The physical domain focuses on the development of a child’s body. Physical skills are important for growth, physical coordination and the movement of the body.

## How do you make a zone fluent?

Re: Creating new zone in Fluent

go to adapt>region and select the region by inputing the coordinates of the boundaries (you can choose between the shapes on the left, you can also unite more regions in order to obtain more complicated geometries-but not too complicated…), then click mark.
