abaqus修改inp直接建立工程
前面已经知道，通过修改以下inp的节点和单元编号，就可以新建模型，可是对于大的工程来说，逐个选取单元进行添加材料以及确定哪步进行填土仍是比较麻烦的（如果工程网格划分好并告知哪些单元好属于哪些材料，哪些单元号在哪步加载）。如果完全在abaqus中建模和计算就没必要看下面的介绍了。
首先建模：

看1好单元体：
*Element, type=C3D8R
1, 50, 14, 48, 82, 11, 1, 12, 46
在有限元中，节点编号呈逆时针排列，应该是看向z轴正方向时节点绕单元形心呈逆时针排列。
通过修改以上inp的节点和单元编号，就可以新建模型。
更进一步，给相应的单元以相应的材料：
在abaqus/cae中操作就是：
新建材料，并赋值参数：
然后建立截面，并对截面选择对应的材料属性或本构，截面是对结构的人设计的，比如梁的设计需要建梁并划分网格太麻烦，这个截面可以方便快速的把界面设计好。对于我们岩土来说这个就是走个流程，反倒是麻烦了一些。
下面将界面赋给对应的模型部分，对于我们岩土来说，相当于把对应的本构模型参数赋值给对应的模型，将来这部分模型划分网格后，这些网格就是这些材料了。
划分网格后，写出input文档，就可以看上面直接写inp和cae操作的对应了。

下面接着进行，看堆载问题如何解决，工程中给出哪个计算步step堆载哪些单元了，那就把这些单元编号分组并写在对应的step中即可：
一般在abaqus中先建立step：
给激活和死掉的单元分组，并由step：
