Error hunt

Reversed normals, empty ESURF, omitted CNCHECK, TYPE/REAL errors, and ignored RFY.

Bug hunt

Five scenarios documented in 11_bug_hunt.mac:

  1. Contact and target surfaces swapped.
  2. ESURF without a prior selection → n_conta = 0.
  3. Omitting CNCHECK → undocumented initial state.
  4. Incorrect TYPE/REAL while creating surface elements.
  5. Accepting SOLVE without reading reactions or contact state.
Quick check

n_conta=0 after ESURF. What is the most likely cause?
