Node recorder for incremental displacement

[hsafti]

Dear all,

For example 22 from the UCSD geotechnical examples of OpenSees, I tried to add a recorder for incremental displacement. Nevertheless, the results are all zeros:

eval "recorder Node -file NodeDispIncX.out -time -nodeRange 1 $NumOfNodes -dof 1 -dT $deltaT incrDisp"
eval "recorder Node -file NodeDispIncY.out -time -nodeRange 1 $NumOfNodes -dof 2 -dT $deltaT incrDisp"

Any help is appreciated.

what version of OpenSees are you using .. the command you posted should work.

Thanks a lot for your response.

I'm using version 2.2.0 for learning. Nevertheless, I will compile a 2.1.0 version because I'll be using the FluidSolidPorous material (as stated in the website http://cyclic.ucsd.edu/opensees/)

I tried the recorder in the 2.2.0 version for a quadUP element.
