the usal way of visualizing data from OpenFoam is to create a file like foam.case in the calculation directory and to import this file. The problem is with this method, that only the data of the internal mesh are displayed in CAESES and that you do not have the values of the boundary faces.
To see these values you can export your OpenFoam data to VTK. This is done with follwowing OpenFoam command:
With this command a new folder called VTK is created with the VTK files of all boundaries and patches. Theses different files can be imported into CAESES and values like Wall Yplus or pressure can be displayed.
Have a great start into the week :-)
