Approximated objective does not match with response at first iteration (ioerr(1897))
Hello,
since a few days i´m trying to do a nonlinear quasi static topography optimization of an simple l-braket and want to form a bead. It has to be nonlinear, because later there will be contacts and other stuff in the complete model.
It´s the first time i´m doing this, so i´m pretty inexperienced. I alway got the same error, approximated objective does not match with response at first iteration (errorcode 1897). I´ve tooked some screenshots with my settings.
It would be really nice if someone knows where my problem is.
Thanks and greetings,
Luca
