Interpretation of .out files

Post by duttaANURAG » Thu Apr 12, 2018 7:19 am

Good Evening,

I am working on Dynamic Wall-Backfill-Foundation Soil Interaction Problems in OpenSees.

Well, I recently started Analysis of Static Wall-Backfill-Foundation Soil Problems. After the analysis we get stress.out,displacement.out,slaveForce.out,frictForce.out,contForce.out,mastForce.out.

Please tell me how to analyse these files contain only values and doesn't indicate to which quantity does these values correspond?

I would appreciate your help a lot.

Thank You.

That would depend on the recorder used and on the material output.
For example, for the PIMY material (http://opensees.berkeley.edu/wiki/index ... d_Material)
it would be, as specified on the material's page : For 2D problems, the stress output follows this order: σxx, σyy, σzz, σxy, ηr, where ηr is the ratio between the shear (deviatoric) stress and peak shear strength at the current confinement (0<=ηr<=1.0). The strain output follows this order: εxx, εyy, γxy.
Remember that if in the recorder command -time was entered, the first column will be the time of the system.

You can display the element response on screen to see what the recorder will return in the output file using command EleResponse (http://opensees.berkeley.edu/wiki/index ... se_Command)
Check this file for more specific details and example : http://opensees.berkeley.edu/wiki/image ... Output.pdf
Hope it helps, GL
