  This Q1, which sets up a steady 2D flow through a passage created
  by blockages, has been set up by means of the general input menu.

  Enter the menu (Type M, return, R) to see the geometry and
  settings, and to change them if desired.

  On re-entering command mode, another means of interpreting the
  settings can be activated by typing: L(20). This is always
  available.

  PHOTON USE commands have been included in the Q1.

  ENDDIS
  DISPLAY

  In this case, the false-time-step rlaxation factors set by
  the General Menu for case 293 are first multiplied by 1.E-3.
  Then LSWEEP is raised to 200.

  This proves to be not enough to secure convergence.
