Hi,

I met the  *** ERROR # 941 *** when I was doing a non-linear analysis. This is material non-linear. No contact or large deformation is defined.
This is the first time I met the problem.

*** ERROR # 941 ***
NON-CONVERGENT NONLINEAR ITERATIONS FOR SUBCASE 1

Suggestions:

(Scratch disk space usage for starting iteration = 621 MB)
(Running in-core solution)

 

Following is the .out file. Thanks for your help.

*** INFORMATION # 1579
for material id = 10 referenced from property id = 1.
MATS1 referred to from MID3 will be ignored - plasticity is
supported for membrane and bending deformation, but not for transverse shear.

*** INFORMATION # 1579
for material id = 10 referenced from property id = 2.
MATS1 referred to from MID3 will be ignored - plasticity is
supported for membrane and bending deformation, but not for transverse shear.

*** INFORMATION # 1579
for material id = 10 referenced from property id = 3.
MATS1 referred to from MID3 will be ignored - plasticity is
supported for membrane and bending deformation, but not for transverse shear.

*** INFORMATION # 1579
for material id = 10 referenced from property id = 10.
MATS1 referred to from MID3 will be ignored - plasticity is
supported for membrane and bending deformation, but not for transverse shear.

*** INFORMATION # 815
The total number of rigid elements, whose rotational dependent d.o.f.
are removed because there is no need to constrain those d.o.f., is 2.

*** INFORMATION # 3433
MUMPS solver is used by default for nonlinear analysis at subcase 1.
