  Hi,
  I am performing a soil-structure-interaction analysis with MAT 79. I got the following errro message:
  ***Error 20166 (STR+166)
  Increasing slope (5.3376E+02) in material type 79. Investigate slope between points 2 and 3 PID 3

  The error message is referring to curve LCID in MAT 79. Remark 4 in the User's Manual's description of MAT 79 states, "The slope of the curve must decrease with increasing gamma."
