The Ansys program contains a sequence of statements in four groups. They can be typed from the graphical interface or read from a batch file. You can use either upper or lower for Ansys, but I use upper case for Ansys commands and lower case for my symbols.
- The header section gives the title that will appear on your grahpics./TITLE, Your name, MENG 421, date here, axial1.a ! comments follow an exclamation point
- The preprocessor section defining the model
/PREP7 . . . FINISH
- The solution section defining the boundary conditions and calculating the primary solution/SOLUTION . . . FINISH
- The post processor section providing additions data
/POST1 . . . FINISH
Let's look at each of these four groups in more detail.
- The header section has the title that will appear on your grahpics.
- Always include a /TITLE command with your name, the date, and the file name that will appear on the plot.
- Use frequent comments to explain the various commands. Comments follow an exclamation point.
- In the Preprocessor section, /PREP7, you create three tables describing the properties of the elements. Then you define the nodes and the elements.
- The element types, ET
- The real constants, R
- The material properties, MP
- The nodes, N
- The elements, E
- Several nodes can be created at once with the NGEN command.
- Similarly, several elements can be created at once with the EGEN command.
- In the Solution section, /SOLUTION, you define the loads and the constraints.
- Constraints are defined with the D command.
- Loads are defined with the F (concentrated), SFBEAM (beam), and SF (general surface) commands.
Additional Ansys source files are available in the following directories on the Tech file server:
- ~es421/class/ (Linux)
- C:\Program Files\Ansys inc\ansys57\data\verif (Windows 2000)
