  • aa_r is a "ANSYS Academic Research License" with 16 inclusive tasks. Research jobs with more than 16 tasks cost additional "aa_r_hpc" licenses.
  • aa_t_a is a "ANSYS Academic Teaching License" with a maximum of 16 tasks. These may be used only for student projects, student instruction and student demonstrations. Eligible users are allowed to activate these, by adding the flag

    Codeblock
    titleActivation 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
    titleRedefining 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.
