HI,

CAN Someone tell me how I may solve a fatigue Subcase which references a Non-linear Fat load.I was able to do fatigue analysis of some part which referenced a linear subcase but in case of fatigue which references a Nonlinear subcase I get the error below.

*ERROR

-------------------------------------------------------------------

A fatal error has been detected during input processing:

*** ERROR # 6964 ***

Subcase 4 referenced in FATLOAD card 8 is not a linear static subcase.

*** Run terminated because of error(s) in the input data.

    Hello,

    it seems that only linear static subcases are supported.

    Look into the online help:

    FATLOAD parameter

    LCID: Subcase identification number of a linear static solution subcase.

    Regards,
