# What is the unit of density in Abaqus?

## What is the unit of density in Abaqus?

Example

Commonly used unit | SI value | |
---|---|---|

Density of steel | 7850 kg/m3 | |

Gravitational constant | 9.81 m/s2 | |

pressure | 1 bar | 105 Pa |

Absolute zero temperature | -273.15 ̊C | 0 K |

## How do you use density in Abaqus?

For instance:

- 1 force unit = 1 mass unit * 1 acceleration unit.
- 1 acceleration unit = 1 length unit / (1 time unit)^2.
- 1 density unit = 1 mass unit / (1 length unit)^3.

**What are Abaqus units?**

Abaqus has no built-in system of units. Do not include unit names or labels when entering data in Abaqus. All input data must be specified in consistent units.

**What is the time unit in Abaqus?**

Abaqus has no default system unit, it is a user choice. You have to choose three base units: length/mass/time. For instance it can be SI system unit [m/kg/s] or [mm/kg/ms], [mm/ton/s].

### What is the unit of temperature in Abaqus?

Symbols used in ABAQUS for units

Dimension | Indicator | Example (S.I. units) |
---|---|---|

temperature | degree Celsius | |

electric current | A | Ampere |

force | F | Newton |

energy | J | Joule |

### How do you write dimensions in Abaqus?

From the tools in the Sketcher toolbox, select the dimension modification tool . For a diagram of the tools in the Sketcher toolbox, see The Sketcher tools. Select the dimension you want to change. Abaqus/CAE highlights the selected dimension and opens the Edit Dimension dialog box.

**How do you give temperature in Abaqus?**

Specify temperature as a predefined field. This option is used to specify temperature as a predefined field during an analysis. To use this option in a restart analysis of Abaqus/Standard, either TEMPERATURE or INITIAL CONDITIONS, TYPE=TEMPERATURE must have been specified in the original analysis.

**How do you find the dimensions of a part in Abaqus?**

From the bottom of the Sketcher toolbox, select the Sketcher customization tool . The Sketcher Options dialog box appears. Click on the Dimensions tab. Abaqus/CAE displays the Dimensions tabbed page.

#### What are the default units in Abaqus?

ABAQUS runs without any units – all numbers. You can understand this as: 1) All of the units are SI, such as Newtons, Pascals and meters. 2) You can then scale these units and it’d also work – if your input is in millimeters and Newtons, then you get kilo-Pascals.

#### What is the correct unit for density in Abaqus?

For density, if you are defining your geometry let’s say in mm and Modulus of elasticity value in N/mm^2 then your density value must be in N/mm^3. As pointed out, Abaqus do not have a pre-assumed unit system to work with. You have to be consistent with your units throughout your model setup. Perhaps I was not clear in my question.

**What are the dimensions of Abaqus’density?**

Since Abaqus has no built-in dimensions, you must ensure that the density is given in consistent units. The use of consistent units, and density in particular, is discussed in Conventions .

**Why quantities in Abaqus have no units?**

For every beginner users, it is really strange that why quantities in Abaqus have no units. They get confused about the stress unit or when inputting parameters like Young Modulus, density… Not only Abaqus, almost any finite element programs (Ansys, LS-Dyna…) do not consider the units of given quantities.

## What is the Young modulus in Abaqus?

We enter 1.16 e+3 as Young Modulus in Abaqus. Remember that you are doing numerical calculation in Abaqus, and 3 mm and .003 m are different for computer; it needs more memory to save and doing calculates on .003 than 3. The following table provides examples of consistent systems of units.
