Limitations

sse, spd, scd, rpl, ddsddt, drplde, drpldt, predef, dpred, drot, pnewdt, celent, layer, kspt. If you need these fields, contact “dhondt@t-online.de”. Furthermore, the following fields have a different meaning:

• in the linear version:
  • stran:
    • in CalculiX: Lagrangian strain tensor
    • in ABAQUS: logarithmic strain tensor
  • dstran:
    • in CalculiX: Lagrangian strain increment tensor
    • in ABAQUS: logarithmic strain increment tensor
  • temp:
    • in CalculiX: temperature at the end of the increment
    • in ABAQUS: temperature at the start of the increment
  • dtemp:
    • in CalculiX: zero
    • in ABAQUS: temperature increment
• in the nonlinear version:
  • temp:
    • in CalculiX: temperature at the end of the increment
    • in ABAQUS: temperature at the start of the increment
  • dtemp:
    • in CalculiX: zero
    • in ABAQUS: temperature increment

Notice that CalculiX uses double precision. Furthermore, it is good practice to use “implicit none” instead of “implicit real*8(a-h,o-z)”. Therefore it is advised to use “implicit none” in your ABAQUS routine and to declare all reals with “real*8”.
