前面已經知道，通過修改以下inp的節點和單元編號，就可以新建模型，可是對於大的工程來說，逐個選取單元進行添加材料以及確定哪步進行填土仍是比較麻煩的（如果工程網格划分好並告知哪些單元好屬於哪些材料，哪些單元號在哪步加載）。如果完全在abaqus中建模和計算就沒必要看下面的介紹了。
首先建模：

看1好單元體：
*Element, type=C3D8R
1, 50, 14, 48, 82, 11, 1, 12, 46
在有限元中，節點編號呈逆時針排列，應該是看向z軸正方向時節點繞單元形心呈逆時針排列。
通過修改以上inp的節點和單元編號，就可以新建模型。
更進一步，給相應的單元以相應的材料：
在abaqus/cae中操作就是：
新建材料，並賦值參數：
然后建立截面，並對截面選擇對應的材料屬性或本構，截面是對結構的人設計的，比如梁的設計需要建梁並划分網格太麻煩，這個截面可以方便快速的把界面設計好。對於我們岩土來說這個就是走個流程，反倒是麻煩了一些。
下面將界面賦給對應的模型部分，對於我們岩土來說，相當於把對應的本構模型參數賦值給對應的模型，將來這部分模型划分網格后，這些網格就是這些材料了。
划分網格后，寫出input文檔，就可以看上面直接寫inp和cae操作的對應了。
