For driving the flow type database, there are 4 classes of flows, and then flow_tags, all of which are set in the meta-data block at the end of the case description page. === Flow classes === dbcase classes that can be set (a case can be in more than one of these): free_flow flow_around_body semi_confined_flow confined_flow ===Flow tags=== The flow tags tested for in each of the above classes (a case can include any number of them): **free_flows**: homogeneous, mixing_layer, jet, wake, curvature, rotation, unsteady, scalar **flow_around_body**: 2d, 3d, streamlined_body, bluff_body, tube_array, unsteady, fsi **semi_confined_flow**: 2dbl, 3dbl, surface_mounted_body, transition, separation, curvature, rotation, jet, unsteady, scalar, buoyant **confined_flow**: 2d, 3d, channel_flow, constant_cross_section, varying_cross_section, separated, swirl, curvature, rotation, unsteady, scalar, buoyant
