Tecplot 帮助手册

  1. 打开 tec360.exe—Help—Data Format Guide
  2. 或者直接搜索并打开文件：360_data_format_guide.pdf
  3. 主要有两种格式顺序格式/非顺序格式，有限元数据要使用非顺序格式，除非模型比较规则才可以使用顺序格式

variables = "x", "y","z","disp"
zone T=XDD1, nodes=8, elements=1, et=brick, f=fepoint

# 下面对应variables的数值
-1, -1,  0,  1.1
 1, -1,  0,  1.2
 1,  1,  0,  1.3

 1, -1,  1,  1.6
 1,  1,  1,  1.7
-1,  1,  1,  1.8

# 下面是单元连接关系
1, 2, 3, 4, 5, 6, 7, 8

四面体单元

variables = "x", "y","z","disp"
zone T=XDD2, nodes=4, elements=1, et=tetrahedron, f=fepoint
-1, -1, 0, 1.1
 1, -1, 0, 1.2
 1,  1, 0, 1.3
 1, -1, 1, 1.8
1, 2, 3, 4

四边形单元

variables = "x", "y","z","disp"
zone T=XDD3, nodes=4, elements=1, et=quadrilateral, f=fepoint
-1, -1,  0,  1.1
 1, -1,  0,  1.2
 1,  1,  0,  1.3
-1,  1,  1,  1.4
1, 2, 3, 4

三角形单元

variables = "x", "y","z","disp"
zone T=XDD4, nodes=3, elements=1, et=triangle, f=fepoint
-1, -1,  0, 1.1
 1, -1,  0, 1.2
 1,  1,  0, 1.3
1, 2, 3

同时输出多种类型的单元

如果是只有三角形与四边形，把三角形最后一个结点重复两次即可

如果是只有四面体与六面体，把四面体最后一个结点重复四次即可

同时含有 2D 与 3D 单元，将 2D 单元按照 3D 单元来写，想想怎么重复结点即可

如果只要网格，也可以重复上面的文件，比如下面这个同时输出六面体与三角形
