4.3.1 Reading and Writing Case Files

Case files contain the mesh, boundary and cell zone conditions, and solution parameters for a problem. It also contains the information about the user interface and graphics environment. For information about the format of case files see Appendix  B. The commands used for reading case files can also be used to read native-format mesh files (as described in Section  4.2) because the mesh information is a subset of the case information. Select the File/Read/Case... menu item to invoke the Select File dialog box.

File $\rightarrow$ Read $\rightarrow$ Case...

Read a case file using the Select File dialog box. Note that the Display Mesh After Reading option in the Select File dialog box allows you to have the mesh displayed automatically after it is read.

Select the File/Write/Case... menu item to invoke the Select File dialog box.

File $\rightarrow$ Write $\rightarrow$ Case...

Write a case file using the Select File dialog box.

When ANSYS FLUENT reads a case file, it first looks for a file with the exact name you typed. If a file with that name is not found, it searches for the same file with different extensions (Section  4.1.5). When ANSYS FLUENT writes a case file, .cas is added to the name you type unless the name already ends with .cas.
