Increasing output time step increment

[quhui]

Hi, silvia:

I found a strange new question during modifying the proc (I didn't modify nothing else except the

command of recorder). My initial command is:

recorder Node quhui.out disp -load -node 10 -dof 1

I want to output the horizontal load and horizontal displacement of evey increment for node 10. But

when I modify the command as:

recorder Node -file quhui2.out -dT 0.02 -time -node 10 -dof 1 disp,

I found there is no result on unloading and reload cycle. When I modifed the command again as :

recorder Node -file quhui1.out -time -node 10 -dof 1 disp;

The result of quhui1 is equal to quhui.

why? is the problem of my proc?

At last, I want to know if there is even more detail help on recorder command?

thank you!!

you cannot you the -dt 0.02 option in this case .. if the pseudo time at the end of your first push is 10.0, the reecordeer will only record again at time 10.02 .. as you reverse direction at 10.0 and start going the other way the pseudo time is getting smaller, e.g. < 10.0, .. you never get to 10.02 .. you will not record again unless you push to 10.02 and beyond.

Thank you for everyone's help!

I try the recorder command with -dT 0.02 for a proc with monotonic displacement, it work well.

But when I try the command on a cantilever subjected to a cyclic load history, the example in the part of PINCHING4 Uniaxial Material Model Discussion of the manual, it does not work! Why?

The part of analysis in my proc is based of it.

Thank you again!

you should contact the authors of pinching4.

Could you add the -dT function to the documentation?

some features that have not been tested throughly are not documented.
does the feature work? according to the above message it seemed like it wasn't...

[endryus]

I have tried some simple tests and it seems to work...

all right, please give me examples and i will try to include them after i have checked with fmk.
