ABAQUS implementation external material properties

ABAQUS implementation external material properties

ABAQUS implementation external material properties

(OP)
Hello everyone,

I have following problem. I have generated inp file and in the next step i would like to cut material description in inp file and instead of mentioned material data i would like to put in inp file link to the external file where i'm going to paste data which was cuted before from origin inp file. Unfortunetally I have receifed an error. Of course i started calculation from command line (start-->run -->cmd).

Below i described step by step what i did:
1. Model was prepared in Abaqus. Material was defined as well. FEM simulation is run and finish in Abaqus without any problems.
2. I close Abasus and created empty txt file in the same direction where is origin inp file.
3. I open origin inp file and found material description
(* Material=stell.....). I cuted whole material description (without first row where is material name)
4. I paste cuted data to before created txt file.
5. In origin inp file instead of material description i write *insert, input=steel.inp
6. I change txt file name on steel.inp
7. I start command line and wrote
8. I go to the folder where are inp file
9. I write abaqus job=job_name.inp
10. Analysis is starting but after few second is broken (it is visible on task manager --> processes. CPU activity fall down.

Something is wrong but i can not recognise root cause. I will be gratefull for Your hepl.

Best regards,
David
 

RE: ABAQUS implementation external material properties

What you did, seems correct. What are the files saying abaqus wrote ? *.pre, *msg,*dat ? There should be an error message.

RE: ABAQUS implementation external material properties

You need to put the *INCLUDES at the top of the main input file, not near the bottom as you have.

At the beginning instead of *INCLUDES should be rather *INCLUDE

I cuted and pasted both "include" from the bottom to the top. Moreover i have added material description to the file steel
"*Material, name=DP-600" but still simulation doesn't work

Herewith new files
 

RE: ABAQUS implementation external material properties

You've got duplicate *MATERIAL cards in the input file  -remove these and see if it works.

That a legal copy of ABAQUS you have there..?
