  Each specimen is described by a name of the form ABC in which:
     A - material type (short-term params.): {A,B,C,...,Z}
     B - resolution: {g, c, f, v} = {Gross, Coarse, Fine, VeryFine}
     C - bond type: {c, p, u} = {Contactbonded, Parallelbonded, Unbonded}
  Thus, for example, the gross resolution, contact-bonded instance of
  material-A is named "Agc". The specimen-genesis procedures produce the
  following sequence of models (*.SAV):
     Agc-bal core assembly (no cycling)
     Agc-pck nearly frictionless equilibrium
     Agc-iso low isotropic stress
     Agc-flt floaters eliminated
     Agc-spc final specimen (bonded or unbonded)
----------------------------------------------------
  The Brazilian-test procedures operate upon the specimen produced by the
  specimen-genesis procedures (e.g., Agc-spc.SAV), to produce:
  Agc-spc ]=> Agc-bt0 Brazilian-test initialized
          ]=> Agc-bt1 Brazilian-test complete
----------------------------------------------------
  The biaxial-test procedures operate upon the specimen produced by the
  specimen-genesis procedures (e.g., Agc-spc.SAV), and will modify the
  names to correspond with the form ABC_nn where:
     A - material type (short-term params.): {A,B,C,...,Z}
     B - resolution: {g, c, f, v} = {Gross, Coarse, Fine, VeryFine}
     C - bond type: {c, p, u} = {Contactbonded, Parallelbonded, Unbonded}
    nn - confinement: {00, 10, 30, 100} in MPa, but 00 means 0.1 MPa
  to produce:
       Agc-spc ]=> Agc_nn-bw0 biaxial test initialized
               ]=> Agc_nn-bw1 biaxial test complete
====================================================
  Here follow some of the driver files and the SAV files that they produce:
  (a) model Agc (Gross Resolution Contact-Bonded Material A)
        Agc     => Agc-spc
        Agc_ex ]=> Agc-{spc, bt0, bt1}
               ]=> Agc_00-{bw0, bw1}
  (b) model Afc (Fine Resolution Contact-Bonded Material A)
        Afc     => Afc-spc
        Afc_ex ]=> Afc-{spc, bt0, bt1}
               ]=> Afc_00-{bw0, bw1}
  (c) model Agu (Gross Resolution Unbonded Material A)
        Agu     => Agu-spc
        Agu_ex ]=> Agu_10-{bw0, bw1, bw2}
