Field Output Problem

Field Output Problem

Field Output Problem

(OP)
Hello,

I have a strange problem with the Field Output of Abaqus. Actually, I would like to output the results only for a elements set but I can't.

If I use this code into the .inp :

CODE -->

*Output,Field,Variable=preselect
*Elements output,elset=foo_set,Variable=preselect 

What I obtain in the .odb are the results for the whole model, but why (I have already specified that I only want the "foo_set")?

RE: Field Output Problem

(OP)
It was a typing mistake, I'm using "Element" keyword

RE: Field Output Problem

Actually if I use your code,IceBreakerSours, the result is that when I import the ODB into the Abaqus CAE I get a message like that: "there is no valid step data available..."

RE: Field Output Problem

If the analysis did not finish, then you have additional important issues to fix. Assuming the analysis is actually converging, then you should figure this out on your own and the problem is arising because you did not take the necessary time to go through the Getting Started Guide.

You should read through the appropriate section(s) in the Keywords Reference Guide and related pages in the CAE User's Guide; latter might be easier for a beginner.

The analysis did finish if I use this code (so there is no problem with it):

CODE -->

*Output, Field,variable=preselect
*Element Output, elset=foo_set 

But when I try to generate a report it shows the whole model and this is not normal because I have already specified the "*Element Output" keyword. I have already red the documentation and I found no solution yet.

When I change the code to:

CODE -->

*Output, Field
*Element Output, elset=foo_set
S, U, .. .. .. 

I get the error message I told you. Even if if do a simple analysis (a cantilever beam) to test the code it doesn't work.

RE: Field Output Problem

(OP)
No, it doesn't work. This one neither :

CODE -->

*Output, field
*Element Output, elset=foo_set,directions=yes
E, 

The error message when I open the ODB into the viewer or CAE (if I try to plot the deformed shape) :

CODE -->

There is no valid step data available on the database. If the analysis is running, the database must be closed and reopened once the results have been initialized. The requested operation has been cancelled. 

On the contrary, this one works :

CODE -->

*Output, field,variable=preselect
*Element Output, elset=foo_set,directions=yes,variable=preselect 

No problem here to plot the deformed shape or anything I want, but as I said before I have the whole model in the report.

RE: Field Output Problem

Have a look at your .dat file and read the warning messages.
