Strain Recorders in Brick Element

[dks]

Hello,

I need to know the format of the strain output generated for a brick element especially when Ive 2 different brick elements involved.

My script goes like this:

recorder Element -eleRange 1 465 -time -file epsilon_All_1.eps material 2 strain;

My elements 450 to 465 are of material 1 and 1 to 450 are material 2. How to correctly define recorders for them which can give strains at all gaussian points??

Help of any form will be highly appreciated.

Thanks

for the strains at all gauss points with a stdBrick element use
recorder Element -eleRange 1 465 -time -file epsilon_All_1.eps strains

Thanks a lot Sir. Does this hold good for stresses too?

[fmk]

indeed it does.

Thanks for your time Sir!

One more query Sir. Does it give output in format 11 22 33 12 23 13 from element 1 to 465 at gauss point 1 and then follows the same format for gauss point 2 and so on ,or it follows any other pattern---say like starts with element 1: 11 22 33 12 23 13 for Gauss Points 1 to 8 simultaneously(means 48 values at a time for each element ) and then moves to next element.

If you want to know the output just save it as an xml file that will tell you what each column is. All you need is to change '-file' to '-xml' and have the extension as .xml

Thanks brag006.
This is what I got:

It makes me conclude that it gives all 48 strain values (at 8 gauss points) for each element at once. But the format is 11 22 33 12 13 23 and not 11 22 33 12 23 13 as mentioned in other posts by fmk sir. Is it right? I'm using bbar brick element by the way.

I always thought what it says in the xml file is what you get unless frank has another explanation
