change material properties using Field variables in Abaqus

Hi Everyone,

""""

I was apply Field Variables to change material properties in simulation, but I got this error:


in keyword *FIELD, file "Job-2-Copy.inp", line 5575: Unknown assembly node set _Pickedset2

in keyword *FIELD, file "Job-2-Copy.inp", line 5612: Unknown assembly node set _Pickedset2

in keyword *FIELD, file "Job-2-Copy.inp", line 5643: Unknown assembly node set
_Pickedset2

in keyword *FIELD, file "Job-2-Copy.inp", line 5674: Unknown assembly node set
_Pickedset2

A procedure option is missing for step

THE PROCEDURE CARD *dynamic, explicit MUST BE SEPARATED FROM PREVIOUS STEPS BY AN *ENDSTEP CARD

Step
definition cards between *end step and *step are
ignored. If model definition keywords are defined after the *end step
keyword then they should be moved to the model definition portion of the
input file. If this is a restart analysis check for any unsupported
model definition keywords.

""""""

I
want to change fracture energy in 4 steps. First, I create model,
assembly, load, steps and meshing in Abaqus/CAE, Then add Field
variables in Input file, But I got above errors.
Please help me.

I am not sure about this, but for I received error message like this before I think you may be defined the set name differently:

 Explanation:

You have to insert the following comment on the last line of each step to change the materials

*FIELD 

[setname],[materials dependecy number]

but setname should be according to instance set name not the name you assigned in the geometry part! Let say if your model name is (model1) and you defined a set like (test) then in the [setname] part you should type:

model1-1.test, [dependency number]

here model1 is the name of your model (you can change it BTW) and -1 is about the instance number so these two should come before the geometry name of the set.

 

I hope this helps.
