  Codeblock
  title Activation of the aa_t_a license
  -lpf $ANSYSLIC_DIR/prodord/license.preferences_for_students_and_teaching.xml

  to the Ansys executable, such as "cfx5solve". The path $ANSYSLIC_DIR is provided after loading any Ansys module. Alternatively, eligible users are allowed to redefine their command "cfx5solve" with

  Codeblock
  title Redefining cfx5solve for students
  source $ANSYSLIC_DIR/cfx5solve_redef_with_student_lic

  after loading the Ansys module inside the job script. This will prepend the flag "-lpf ..." to "cfx5solve" automatically if less than 17 task are requested.
