Yes, I guess so.  I don't have any personal experience of this format
myself, but from the Gmsh documentation (same URL), it says

  The values are given by time step, by node and by component, i.e.:

          comp1-node1-time1, comp2-node1-time1, comp3-node1-time1,
          comp1-node2-time1, comp2-node2-time1, comp3-node2-time1,
          comp1-node3-time1, comp2-node3-time1, comp3-node3-time1,
          comp1-node1-time2, comp2-node1-time2, comp3-node1-time2,
          comp1-node2-time2, comp2-node2-time2, comp3-node2-time2,
          comp1-node3-time2, comp2-node3-time2, comp3-node3-time2,
          ...

so for VQ I guess it's like {u1, v1, w1, u2, v2, w2, u3, v3, w2, u4,
v4, w4} if the vector has components (u, v, w) and the number-suffix
denotes the node in the quadrilateral.  Does that make sense in terms
of your data?
