4.3.3 Reading and Writing Case and Data Files Together

A case file and a data file together contain all the information required to restart a solution. Case files contain the mesh, boundary and cell zone conditions, and solution parameters. Data files contain the values of the flow field in each mesh element and the convergence history (residuals) for that flow field.

You can read a case file and a data file together by using the Select File dialog box invoked by selecting the File/Read/Case & Data... menu item. To read both files, select the appropriate case file, and the corresponding data file (same name with .dat suffix) is also read. 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.
