When running Fluent in Workbench, Fluent will save images corresponding to all post-processing activities in the tree (contours, vectors, pathlines, xy-plots) at the end of calculation or if calculation is interrupted. This process can take dozen seconds, if a lot of contours or xy-plots have been defined. No workbench options have been defined yet to avoid this behavior. This may come in future release .The workaround (at release 19.1 and before) consists in adding the following lines in your .fluent file. (Create one if it doesn’t exist already) Lines to add in “.fluent”: (in-package graphics-manager (define-method (save-images) (pp “Ignoring ‘save-images’ function call”) )) Note that home directory on windows is: c:usersuser_name
