Placing Multiple Recorders into Single File

[aliakbar]

Dear all,

I have some time history results (max/min envelope result for each run of the loop) for a group of ground motions. I want to make Opensees write all the results into a single output file instead of placing each of them into a separate file which makes it very difficult to manage. Is it possible to do this?
Please guide.

Thanks

In your OpenSees file, you can add commands to read from the recorder file and append that information to another file in the for loop

Dear Aliakbar,

I have 2 acceleration ground motions for x and y directions, I want to record result of each ground motion separetly, because when I have 1 recorder for both directions, I think maybe the results are wrong. is it possible to help me how to write 2 recorders for my 2 acceleration ground motions?
here is my code with 1 recorder:

# recorder time step
set recDT $motionDT

## record nodal displacments, velocities, and accelerations at each time step
recorder Node -file displacement.out -time -dT $recDT -nodeRange 1 $nNodeT -dof 1 2 3 disp
recorder Node -file velocity.out -time -dT $recDT -nodeRange 1 $nNodeT -dof 1 2 3 vel
recorder Node -file acceleration.out -time -dT $recDT -nodeRange 1 $nNodeT -dof 1 2 3 accel

# record stress and strain at each gauss point in the soil elements
recorder Element -file stress.out -time -dT $recDT -eleRange 1 $nElemT stress
recorder Element -file strain.out -time -dT $recDT -eleRange 1 $nElemT strain
