limitation on the number of recorders

[alirezacivil]

Is there any limitation on the numbers of recorders using OpenSeesSP?
The recorders work individually but not together!

what do you mean by not together.

Hi,
Thanks for your response.

I am modelling a 12 storey building in 3D. The beam/column elements are elastic elements with concentrated hinges using zero length elements and shear walls are modelled using displacement beam column elements.
I wanted to record each node rotations. When I use the recorder commands for one node it works. But when it comes to recording all of the nodes, it has some errors.

[fmk]

what are the errors?

Hi,
Thanks for your response.

When I record the nodes in separate files ( each node in separate node command) opensees freezes. Without progressing in the analysis, it starts writing in the results folder and if I do not stop it, the volume of this folder can reach to 10 GB.

But I found the solution. I should write all of the node tags in one command of recorder. Then it is fine.

numbers of recorders , can we have genuine information about this?

Hi,
I obtain the same results than alirezacivil . If I use a sentence with "foreach" like this:

foreach gp {1 2 3 4}
recorder Element -file "Outputs/Plates/ele59sec1forcegp $gp.out" -time -eleRange 260 603 material $gp forces
recorder Element -file "Outputs/Plates/ele59sec1defgp $gp.out" -time -eleRange 260 603 material $gp deformations
}

The dynamic Analisis doesn't work, but if I use the same sentence without foreach works, like this:
recorder Element -file "Outputs/Plates/ele59sec1forcegp1.out" -time -eleRange 260 603 material 1 forces
recorder Element -file "Outputs/Plates/ele59sec1defgp1.out" -time -eleRange 260 603 material 1 deformations
recorder Element -file "Outputs/Plates/ele59sec1forcegp2.out" -time -eleRange 260 603 material 2 forces
recorder Element -file "Outputs/Plates/ele59sec1defgp2.out" -time -eleRange 260 603 material 2 deformations
recorder Element -file "Outputs/Plates/ele59sec1forcegp3.out" -time -eleRange 260 603 material 3 forces
recorder Element -file "Outputs/Plates/ele59sec1defgp3.out" -time -eleRange 260 603 material 3 deformations
recorder Element -file "Outputs/Plates/ele59sec1forcegp4.out" -time -eleRange 260 603 material 4 forces
recorder Element -file "Outputs/Plates/ele59sec1defgp4.out" -time -eleRange 260 603 material 4 deformations
