About recorder comands (EnvelopeNode)

[miyauchi]

Hello.
I commented because I do not know how to use the recorder command(envelope node,envelope element) and I can not output the data well.

I'll try to code it like this:
ops.recorder('EnvelopeNode','-file','Node_disp_max.csv','-timeSeries', 1 ,'-node',0,1,2,3,4,5,6,7,8,'-dof',1,'disp')

Then, a file named "Node_disp_max.csv" will be output.But it's empty inside.

Then edit as follows and run(Remove the - from '-file'.):
ops.recorder('EnvelopeNode','file','Node_disp_max.csv','-timeSeries', 1 ,'-node',0,1,2,3,4,5,6,7,8,'-dof',1,'disp')

Then the result is output to the csv file created in the first sentence.

Why doesn't the first statement print any results?
Please tell me how to output the analysis result at once using EnvelopeNode.

Please post a minimal working example that demonstrates the issue.
