element and envelope element recorder

[Ricsey]

Dear all!

I have a question about the Element and EnvelopeEnvelope recorder.

I've tried to get a column internal forces, but I cannot figure out the output file format. I tried to record 13 elements (14 nodes) internal forces, but in the output file, I get 78 column datas, but I wait 13(elements)*2(start and end node)*6(dof) = 156 column data.
I checked the format of the outputs with xml format, and I see opensees wants to output elements*2*6 datas, but only the half is written in the file? Are these the starting or ending node results?

recorder Element -xml "element.xml" -ele 1 2 3 4 5 6 7 8 9 10 11 12 13 -dof 1 2 3 4 5 6 globalForce
recorder EnvelopeElement -xml "elementenvelope.xml" -ele 1 2 3 4 5 6 7 8 9 10 11 12 13 -dof 1 2 3 4 5 6 globalForce

Am I thinking right if this is a bug?

Oh, and in the envelope recorder I have 13 columns? How???

Note: This is recording a ForceBeamColumn3d element.
