FoamX at start-up will look through through a predefined set of directories to find directories with a FoamX subdirectory. These directories are taken to be utilities or solvers which need to be added to FoamX. For solvers it looks through directories

  • $WM_PROJECT_DIR/applications/solvers
  • $WM_PROJECT_USER_DIR/applications/solvers,

for utilities it looks through directories

  • $WM_PROJECT_DIR/applications/utilities
  • $WM_PROJECT_USER_DIR/applications/utilities.

The easiest way is to copy the FoamX directory of an existing solver/utility and rename the top .cfg file to your solver. Make sure that the

  • directory name
  • top level solver name
  • .cfg file in the FoamX directory

are all consistent.

For example, if your application is similar to icoFoam, take


and copy it to


where myFoam is the name of your new solver and move




Adapt the configuration file and the dictionaries to your needs and change /Make/files to match your application name.

Create a case (right click on the root directory in the case browser) and you will have myFoam to choose from.
