## What is axisymmetric in abaqus?

Abaqus includes two libraries of solid elements, CAX and CGAX, whose geometry is axisymmetric (bodies of revolution) and which can be subjected to axially symmetric loading conditions. In addition, CGAX elements support torsion loading.

### How do you create an axisymmetric model in Abaqus?

Create new axisymmetric part Go to the Part module, select Part à Create and select Axisymmetric as modelling space (Figure 10). The sketch module is now opened. Select the Add Sketch tool (Figure 11) and choose the sketch that was just saved. You now have the option to reposition entities.

What is an axisymmetric component?

Axisymmetric elements are triangular tori such that each element is symmetric with respect to geometry and loading about an axis such as the z axis. Hence, the z axis is called the axis of symmetry or the axis of revolution. Each vertical cross section of the element is a plane triangle.

What are the conditions for a problem to be axisymmetric?

The problems in which the body possesses an axis of symmetry and the boundary conditions and other parameters of the problem are symmetric with respect to this axis are called as axisymmetric problems. The cylindrical coordinate system is found to be convenient for analyzing such problems.

## What is meaning of axisymmetric?

symmetric in
: symmetric in respect to an axis.

### What is axisymmetric model?

Axisymmetric modeling allows the user to analyze a 3-D excavation which is rotationally symmetric about an axis. The input is 2-dimensional, but the analysis results apply to the 3-dimensional problem. Note: Because of the symmetry, only “half” of the problem needs to be defined.

What is meant by axisymmetric solid?

Definition of an axisymmetric solid ➢ An axisymmetric solid (or a thick-walled body) of revolution is defined as a 3-D body that is generated by rotating a plane and is most easily described in cylindrical coordinates. Where z is called the axis of symmetry.

What is cylindrical symmetry?

In cylindrical symmetry, there is only one axis of rotation, and it is always vertical. Cylindrical symmetry is commonly found in towers, columns, and domes.

## How to do a data check in Abaqus?

A data check analysis is performed by using the datacheck parameter in the command for running Abaqus (see Abaqus/Standard and Abaqus/Explicit execution ).

### Can a nonaxisymmetric element be used in an axisymmetric model?

First- and second-order elements cannot be used together in the axisymmetric model. Nonaxisymmetric elements such as springs, dashpots, beams, and trusses will be ignored in the model generation. Only surface-based contact pairs can be revolved. Models using general contact cannot be revolved.

Which is a field variable in Abaqus temperature?

In ABAQUS temperature can either be a field variable (stress analysis, mass diffusion, …) or a degree of freedom (heat transfer analysis, fully coupled temperature-displacement analysis, …). For any analysis that involves temperature, you can request the temperature either at nodes (variable NT) or in elements (variable TEMP).

When to restart the old model in Abaqus?

The name of the restart files from the old model must be specified when the new analysis is executed by using the oldjob parameter in the command for running Abaqus or by answering a request made by the command procedure (see Abaqus/Standard and Abaqus/Explicit execution ).
