发帖数: 133 | 1 刚开始学ABAQUS, 版本是6.5-1, 随便找了个自带的EXAMPLE, 用ABAQUS读里面的*.INP,
结果出来一些WARNING, 比如:
WARNING: The following keywords/parameters are not yet supported by the input

ABAQUS里有象ANSYS里面那种在GUI界面下一条条输入KEYWORD指令的么?
我找了半天好象没有. ABAQUS的CAE做的比较差?

性。它CAE借鉴了很多三维设计软件的思想，反正我是挺习惯的，CAE里没有的keyw
ords可以自己在数据文件里加。

。
如果是说这些的话，Abaqus' CAE 不要说是什么far superior than others,我都可以说
v6.3以前它明显属于比较烂的那种。不过据说6.4以后终于可以在pc上脱离exceed了，
应该有很大进步。

发帖数: 126 | 9 try build a couple of and modify a couple of nonlinear model and do some
parameteric study using both patran/ansys/abaqus pre-post, you wll see the
difference. the feature based, object oriented framework from CAD software
just would save you tons of time and effort.

发帖数: 57 | 10 hehe，maybe the best way to prove yourself is making some detail comparison.
abaqus' nonlinear solver is great,but pre-post is just so so.
I have many years of experience on those fea softwares.For abaqus,i'd say i
am not very familar with v6.4 and v6.5, but it is really inconvinent to make
complex model before v6.3.
If abaqus got solid pre-post processor, why it bother to make a big interface
for patran and hypermesh? I don't think it is just for model compatible.

一个结构, 比如说一个轮胎, 我想每次计算把它的内外径稍微变变, 有什么办法么?
好象在GUI--PART MODULE里面建了PART后就不能改了

发帖数: 126 | 15 abaqus cae is not complete, but its feature based system is revolutionary in
major fem packages. none of the famous pre processors, hypermesh, patran,
ansys
etc, are not feature based.
give you the example
you created a cube solid, then later you want to change its size, in all
other package, you would either 1. delete the cube and recreate from scratch
2. create/record the macro to create the cube, save the macro as a file,
use text editor to edit the script, put different size value in, run th

发帖数: 57 | 16 It is an interesting feature but not neccessary.
Either ansys's input script or patran's PCL script is very strong.
For your case, its just a simple parametic design. Just make a parametic
script,you can remodel any objects without hussle. Thats how the optimization
modula in ansys do. I always think making script is the best way to maintain
your model.
Whats more, there's some shortcoming for such kind of feature based design.For
Example,if you have sphere A and B,they contact at a single poi

发帖数: 126 | 17 it does not make much different in school, huge different in industry when
you create module from scratch instead of importing from CAD files.
if you have tried patran pcl, you will know how difficult and time consuming
it is to make even simple change. and if the model is a little complex, often
the script just goes nowhere or behave unpredictably.
don't take my word, do a little practic youself. as I said, do some
modification
and see how much time it takes to do in ansys/patran compared with

发帖数: 204 | 18 是*.inp. 直接用文本编辑器加啊。
先用CAE做掉大部分的建模工作，再在用CAE生成的*.inp文件里自己加入一些特定的
关键字。比如说奇异性啦，弹簧连接啦什么的。
