Creating field output- CAE help needed

Creating field output- CAE help needed

Creating field output- CAE help needed

(OP)
Hi,

I am trying to create a field output in my abaqus model. Is there a way in which to create a field output for results belonging to selected subset of elements and is it possible to select these elements in the active viewport.(my model is set-up on an orphan mesh - no parts)

The problem I am running into, when generating the output, is that I am getting the error message : "division by zero". I may be able to go around it by operating on selected elements if that is possible.

Thanks in advance
SS

Hi Satyasrinivas,

I think you have to define a "node set" or "element set" in your assembly first. Then create a field output specifically for this set. You can choose which set to output (default is "whole model")

Thanks Ccheric. That works.

Hi Ccheric,

A follow up question - is it possible to create a  field output for all the increments in the model by writing one expression.

Right now, I have to write the expression as many times as there are increments of interest (and there are lots of them).

Thanks
SS

RE: Creating field output- CAE help needed

Your question sounds interesting, because it's the reverse of the usual way.

By default, field output is printed every increment. i.e. frequency = 0

If you want to optionally print output at selected increments or at the end, you write something different.

Am I misreading your question?

p.s.
this is how my default output lines look like, it outputs everything every increment:


** OUTPUT REQUESTS
**
*Restart, write, frequency=0
**
** FIELD OUTPUT: F-Output-1
**
*Output, field, variable=PRESELECT
**

HI Ccheric,

             Thanks for the response.

I actually wanted to know if it is possible to create a field output (after the analysis is finished) for all the increments - using only one expression in the create field output tool.

Presently, I have to create a new field output for every increment of interest. I wish I could create a field output for all the increments with one expression. Please let me know if that is possible.

For eg., I want to create a new field output (EE11+IE11) (sum of max. elastic and inelastic strains) and see how it varies with each increment of deformation. Instead of creating a new field output for every increment, is there a way to create this field for all the increments in one go.

Hope I could convey my question.

Thanks,
Rajesh

Hmmm... If I'm reading the question right, it seems like you want to take your outputs and augment them together into, lets say, a graph? If this is the case, in the ODB viewer, you should be able to go to "create XY Data" and "Operate on XY Data", and use the functions to add your outputs. This would enable you to plot the summation of EE11 and IE11 for every incriment that Abaqus wrote data for.

Thanks Nileo2005...I will try that..
