Time integration in transient diffusion analysis is done with the backward Euler method also referred to as the modified Crank-Nicholson operator. Abaqus Scripting Interface object: It also discusses the utility routines that can be used when coding subroutines.
Abaqus 6.9 Supported Platforms & Products
The first step establishes an initial steady-state concentration distribution of a diffusing material. It may be useful documentatikn run these problems when learning to use a new capability. This chapter describes the installation procedures for Abaqus documentation, licensing, and products, as well as the procedures to uninstall these components. The governing equations for mass diffusion are an extension of Fick’s equations: For example, a diatomic gas that dissociates during diffusion can be described using Sievert’s law: You can click on a method to view its description in the command reference.
These values affect only field-variable-dependent material properties, if any. To search for a particular word or phrase near another word or phrase, use the Display occurrences within menu button. Use the following docummentation to specify a concentrated concentration flux at a node: If you choose fixed time incrementation, fixed time increments equal to docuemntation size of the user-specified initial time increment,will be used.
In transient analysis using first-order elements the solubility terms are lumped, which eliminates such oscillations but can lead to locally inaccurate solutions for small time increments. Typical cases are large motion of an elastic-plastic pipe hitting a rigid wall; inelastic buckling collapse of a thin-walled elbow; explosive loading of an elastic, viscoplastic thin ring; consolidation under a footing; buckling of a abaqks shell with a hole; and deep drawing of a metal sheet.
It also discusses docmuentation utility routines that can be used when writing user subroutines.
In the following list of modified commands, the full path to the method is listed along with the required and optional arguments. Modifying or removing concentration fluxes. If you select the User subroutine names search filter, the search function finds only cases where the word is used as the name of user subroutine CREEP.
This manual describes how to use the Abaqus Interface for Moldflow, an interface program that creates a partial Abaqus input file by translating results from a Moldflow polymer processing simulation. Whole or partial model variables: The diffusion problem is defined from the requirement of mass conservation for the diffusing phase: In addition, the supplied input data files provide good starting points to check the behavior of elements, materials, dpcumentation.
To remove unwanted terms from the search, enter those terms in the Without the text field of the Advanced Search window. By default, no backup versions are created. A mass diffusion analysis: Spurious oscillations due to small time increments. The server computers that you choose for documentation and licensing should be accessible by all computers on the network where you plan to run Abaqus and should be stable machines that are not frequently rebooted or shut down.

Using Abaqus Online Documentation. In the final step a temperature field is read from a fully coupled temperature-displacement analysis and the transient mass diffusion response is calculated for the case of heating and cooling documenyation body in which diffusion occurs. Use the following option to define a nonuniform distributed concentration body flux: Interference Fit is an example of GUI text. Use the following input to define a nonuniform distributed concentration body flux: This manual contains a complete description of all the user subroutines available for use in Abaqus doccumentation.
Green italic text Changed argument; for example, the argument type has changed or the possible values of the SymbolicConstant abzqus changed. This manual contains a complete description of each command in the Abaqus Scripting Interface. This method is unconditionally stable for linear problems. Getting Started with Abaqus: If smaller time increments are required, a finer mesh should be used in regions where the normalized concentration changes occur.
This time scale is often convenient for output identification and for specifying prescribed normalized concentrations and fluxes with varying magnitudes. Narrowing the focus of a search, Section 4. Abaqus Scripting Reference Manual.
By default, subdirectories are searched. Many examples are provided to help you develop your own scripts.
The value of an Abaqus parameter. This document contains brief abaqks of the new features available in the latest release of the Abaqus product line. FixedIncrement size: Specifying predefined field variables. In addition, an Abaqus plug-in is available that provides a graphical interface to the upgradeScript method. This manual provides a command reference that lists the syntax of each command in the Abaqus GUI Toolkit. This manual dcumentation a description of the Abaqus Scripting Interface, which is an application programming interface API to the models and data used by Abaqus.
Use the following commands or option to run the script: In nonlinear cases iteration may be necessary to achieve a converged solution. Equilibrium requires the partial pressure to be continuous across an interface, so normalized concentration will be continuous as well. This manual contains detailed examples designed to illustrate the approaches and decisions needed to perform challenging, real-world documenration and nonlinear analysis.
