The forces on all solid BLOCKAGE objects are calculated if CALFOR=T is found in the Q1. This setting can also be made from the Output panel of the VR-Editor Main Menu. The default setting is F (or Off).For further details of what printout is provided please see the entry in TR326.
An alternative to this is the use of the DRAG_LIFT object. A force balance is performed over the six faces of the volume described by the object. The output from the DRAG_LIFT object, which is similar in nature to that described above, is also written to the RESULT file.
