Unable to record stress in Nine Four Node Quad u-p Element

[harshmistry96]

Hi,

I am trying to perform the effective site response analysis in openseespy by following the equivalent code for the same example which is provided for opensees.

I tried recording the stress and strain in element but the file only shows the column for time and it doesn't record any stress or strain. Following is the command for openseespy: op.recorder('Element', '-file', 'stress1.txt', '-time', '-recDT', '-eleRange', 1, nElemT, '-material', 1, 'stress') op.recorder('Element', '-file', 'strain1.txt', '-time', '-recDT', '-eleRange', 1, nElemT, '-material', 1, 'strain')

Please let me know if the implementation is wrong ?

Kind Regards, Harsh Mistry

For now, the inquiry options should be in string:

op.recorder('Element', '-file', 'stress1.txt', '-time', '-recDT', '-eleRange', '1', 'nElemT,' '-material', '1', 'stress')

This will be changed in the future.

Thank you,

also instead of '-material' should it be 'material' ?

Hi,

@zhuminjie, Is it possible to record Excess pore pressure ratio from the Nine Four Node Quad u-p Element, using the following command:

op.recorder('Element','-file','press1.txt','-time', '-dT',recDT,'-eleRange', 1, nElemT,'material','1','pressure')

This option may not be enabled for the recorder of that material. Check the source code of the nDMaterial.
