# Getting Started - CENOS overview

*CENOS Platform* is a simulation software for induction heating. It helps engineers to **save a significant amount of money and time** in induction coil prototyping by replacing physical tests with computer simulations.

In this article we will learn what a simulation is and go over the main points on how to create one.

## What is a simulation?

A numerical simulation or **virtual testing** is a calculation done by a computer following a program that implements a mathematical model for a physical system.

It combines a **geometrical model** of the physical system with the **physics definitions** about that system to predict numerous **physical phenomenon** such as induction heating.

## Simulation with CENOS

CENOS stands for ** Connecting Engineering Open Source**, which highlights the way how CENOS creates and calculates simulations. By combining 3 powerful open-source tools -

**Salome**,

**GetDP**and

**ParaView**- CENOS delivers the best tool for

*Induction Heating*simulations.

The workflow of CENOS simulation is based on these three open-source tools. It consists of 3 parts - **Geometry**, **Physics** and **Results** - representing the steps you need to take to create an *Induction Heating* simulation.

## Geometry

There are 3 ways on how to create and prepare geometry for simulation in CENOS - ** Templates**,

**and**

*From CAD***. These approaches have different geometrical applications and can be used to**

*Advanced geometry editor***prepare any geometry**.

**IMPORTANT**: Along geometry you also need to **prepare a mesh** to carry out a simulation. From mesh quality depends the precision of results - fine mesh will give precise results, while coarse mesh can give inaccurate results. For *Template* and *From CAD* the **mesh is being generated automatically**. For more advanced users *Advanced geometry editor* gives the possibility to create the mesh manually.

### Template

##### note

Fast heating estimations and only a couple of minutes to create

*Template* allows you to choose from **different workpiece and inductor templates** to quickly set up a 2D axial-symmetric simulation.

As the **mesh is being created automatically**, you only need to define the key geometrical and physical parameters to set up a simulation.

### From CAD

##### note

Import premade CAD and simulate it without additional geometrical modifications

*From CAD* is a geometry creation approach which allows you to **import one or more CAD files and prepare them** for simulation without manual geometry modifications.

**Create geometrical groups and boundary surfaces**, define physical parameters and run the simulation. Using this approach, **mesh is being generated automatically**!

### Advanced geometry editor

##### note

For advanced users who want to have a full control over geometry and mesh

For more advanced users CENOS offers **fully manual geometry and mesh creation approach** - *Advanced geometry editor*. It allows to create geometry and mesh from scratch in CENOS geometry modeling tool - Salome.

Create custom geometry and a suitable mesh, define domains and boundaries, and **enjoy the full power of CENOS**!

## Physics

CENOS Platform offers 3 separate physics blocks - ** Thermal Analysis**,

**and**

*Electromagnetics***. Using these physics blocks, you can**

*Induction Heating***simulate and verify different aspects of your induction heating system**.

### Thermal Analysis

##### note

Calculate conventional heating applications

*Thermal Analysis* is a separate physics block for **thermal applications only**. It allows to calculate purely thermal simulations.

### Electromagnetics

##### note

Fast current density, joule heat and other electromagnetic phenomenon predictions

*Electromagnetics* physics block allows you to calculate **purely electromagnetic simulations**. Estimate *Current Density*, *Joule Heat*, *EM field* and other electromagnetic aspects of your model!

### Induction Heating

##### note

Simulate Induction Heating simulations

*Induction Heating* block is coupled electromagnetic and thermal physics block, **designed specifically for induction heating simulations**.

## Results

##### note

Get precise and vast visual and statistical results of your simulation

CENOS incorporates a very powerful post-processor - *ParaView*, which together with .csv file energy statistics provides full control over results and every simulation aspect.
