本书的独特之处在于通过实例学习的方式，引导读者一步步掌握Python编程在ABAQUS中的应用。作者Gautam Puri将专业知识与实践相结合，旨在提供娱乐性的学习体验，而非商业用途。然而，他明确表示，书中提供的信息和示例Python脚本并不保证质量和有效性，且不构成任何质量或适用性担保。
尽管这本书没有得到Dassault Systemes SIMUa Corporation官方的认可，但它提供了丰富的学习资源，适合工程师、科研人员或学生深入理解如何利用Python扩展ABAQUS的功能，进行自动化工作流程或创建定制化的解决方案。通过阅读本书，读者将有机会了解到如何编写Python脚本来控制ABAQUS的模型创建、求解过程、后处理以及结果分析，从而提升工作效率并扩展ABAQUS的使用范围。"
在这个教程中，读者可以期望学到的关键知识点包括但不限于：
1. **Python接口与ABAQUS集成**：了解如何通过Python访问ABAQUS的API，实现对软件功能的无缝控制。
2. **脚本编程基础**：介绍Python语法、数据结构和控制流，确保读者具备基本的编程技能。
3. **模型定义与导入**：学习如何使用Python创建和管理ABAQUS模型，包括几何建模、材料属性设置等。
4. **求解器交互**：探索如何通过Python调用ABAQUS的求解器，控制计算流程，如网格划分、求解策略选择等。
5. **后处理与可视化**：理解如何使用Python读取和解析ABAQUS的结果数据，并进行数据处理和可视化展示。
6. **错误处理与调试**：学习如何处理在Python与ABAQUS交互过程中可能出现的问题，提高代码的健壮性。
7. **案例研究与实践项目**：通过实际项目演示，巩固所学知识，培养解决问题的能力。
这是一本既适合自学又可用于教学的宝贵资源，对于想要在现代工程计算领域利用Python增强ABAQUS功能的专业人士来说，是不可或缺的学习资料。
xtv Preface
completeness (and for those
of
you who are reading because your professor/boss forced
you to), a few uses shall be mentioned.
Let's assume you regularly use a few materials
in
all your simulations. Every time you
start a new simulation
in
the
GUT
mode (Abaqus/CAE) you need to open up the materials
editor and enter in material properties such as
the
Density, Young's Modulus, and
Poisson's Ratio and so on for each
of
these materials. You could instead put all
of
these
materials
in
a script. Then all you would need to do is go to File > Run Script ... and your
material database would be populated with these materials in a couple
of
seconds.
Basically you would be using the script to perform a repetitive task to save time. That is
the one use
of
a script, to perform the same task the same way multiple times with
minimal effort. We will in fact look at this example
of
creating materials with a script in
the first chapter.
A more complex use
of
a script is
if
you have a certain part on which you plan to apply
loads and boundary conditions, and you wish to change the loads, constraints,
or
the
geometry
of
the part itself and rerun the simulation numerous times to optimize the
design. Let's assume for example you apply a load on a horizontal cantilevered beam and
you want
to
know how much the beam bends
as
you increase its length. One way to do
this would be to recreate the beam part 7
or
8 times.
If
your simulation has complex
parameters you might have
to
apply sections, loads and constraints to it every time. A
more sophisticated and efficient way to accomplish the same task is to write a script with
the length
of
the beam assigned to a variable. You could then change the value
of
this
variable and rerun the script in a loop as many times as you need to. The script would
redraw the beam
to
the new length and apply the loads and BCs
in
the correct regions
(accounting for the change in location
of
loads and BCs with the geometry). While this
may sound like too much work for a simple beam simulation,
if
you have a more
complex part with multiple dimensions that are all related to each other then remodeling
it
several times wiiJ prove to be very time consuming and a script will
be
the wise choice.
An added advantage
of
a script is that you have your entire simulation setup saved
in
the
form
of
a small readable text file only a few kilobytes in size. You can then email this
text file to your coworker and
a11
he would need to do is run this script in Abaqus. It
would redraw the part, apply the materials, loads, boundary conditions, create the steps,
and even create and run the
job
if
programmed to
do
so. This also has the advantage
of
readability.
If
a coworker takes over your project,
he
does not need to navigate through
