recording stressstrain is empty, why?

[borjiajia]

Dear Vesna, I have sent my codes in your email,
I have a problem when I recorder stressstrain, the result is always empty after I run it. Is there anything wrong with my recoder codes?

I have tried three ways to record, however, none worked. Could you help me out of this problem?

recorder Element -file $dataDir/ele1122sec3StressStrain.out -Ctime -ele 122 section 3 fiber 0.1 0.1 stressStrain
recorder Element -file $dataDir/ele121sec3StressStrain.out -Ctime -ele 121 section 3 fiber 0.1 0.1 $IDSteelHRB400 stressStrain
recorder Element -file $dataDir/ele121StressStrain.out -Ctime -ele 121section fiber 0.1 0.1 $IDSteelHRB400 stressStrain;

You had a typo in your recorders. Replace them by this:

recorder Element -file $dataDir/ele1122sec3StressStrain.out -time -ele 122 section 3 fiber 0.1 0.1 stressStrain
recorder Element -file $dataDir/ele121sec3StressStrain.out -time -ele 121 section 3 fiber 0.1 0.1 $IDSteelHRB400 stressStrain
recorder Element -file $dataDir/ele121StressStrain.out -time -ele 121 section fiber 0.1 0.1 $IDSteelHRB400 stressStrain;

Oh, I am sorry for my carelessness. Thank you.

I met the same problem with rectangular section, while I can get the stress and strain from circular section.

the file is empty...why?

[vesna]

For the file to be written you have to either exit opensees file or issue wipe command at the end of the file.

[kengawk]

of course, I used wipe so that it can make same data length.

I don't know why...

[vesna]

If that is the case, it seems that your analysis was not completed. You may be having an error somewhere in your script.

I will change to circular section.
I guess it would show something new.
