Facing problem in Element recorder in case of TRUSS

[samdanicivilruet]

Dear All,
I am Samdani, 4th year PhD student at Konkuk University in South Korea.
I am doing research on Seismic performance assessments of nuclear power plant structures.
My structures are combined of nonlinear force beam elements and truss elements.
I want to investigate the force-deformation behavior of the truss members. But the recorder output is not showing the force-deformation of the truss behavior. I have used the following two lines in Recorder file:

recorder Element -xml $dataDir11/47151f.out –time -ele 47151 section 1 force
recorder Element -xml $dataDir11/47151d.out –time -ele 47151 section 1 deformation


However, I checked the output. The following texts are from the output file.

Would You kindly suggest me regarding this issue?
Your responses will be highly appreciated

Try removing the section number from the recorder, i.e., 'section force' instead of 'section 1 force'
