output data to be input

[deran]

Hello everyone,
I am facing a structural problem in ansys, version13.
After the postprocessing of my transient analysis I get, setting the node of interest, a list of results (in my case turn and move along the y axis) to vary the time.
I would now like to be able to insert these results (and specifically the variable potency in time ) as input in an electrical circuit.
What is the command list I can use to take all the results out of the transient analysis and put them in input from one to another (in my case within a circuit ) ?
Please help me because I'm at a standpoint.
thanks in advance:biggrin::biggrin::biggrin::biggrin:

store in a couple of arrays the results of the first analysis and write them on a text file. use these commands:
*cfopen... .
*write. . .
*cfclose
then in the next analysis you read these values and put them as input.
for a more detailed answer try to be more detailed you.

Hello stefano,
first of all thank you for having responded,
I'm practically working on an energy harvesting problem using piezoelectrics.
I built the structural model based on two perfectly glued piezoelectric layers, stuck at the left end and free at the other end.
on the free end I applied an impulse in such a way as to vibrate the piezoelectric.
the piezoelectric generates, at each vibration, a potential, which will therefore be variable over time.
My purpose now is to prove that you can accumulate such potential released by the piezoelectric so as to recharge a small battery.
to do so I could couple the piezoelectric to a circuit, but being the potential variable over time I would need a straightener and the only circuit elements coupled with the piezoelectric are given by the circu94 that do not include the straightener. . So I was trying to reach the problem by building a circuit apart from me, as if it were a new analysis, but I need to put in input, in the source of the potential ( given to this point for the new analysis from the elements set with the circu124 ), the potential that I get out from the vibration of the piezoelectric... but I don't know how to do it to ansys, that is, I don't know how to create an array with the output data, and especially I don't know how to say, through command list, that this array must go into input to the source of the circuit taken for the new analysis.
I am reading in guides, through online papers but I can't solve the problem....necessary help:redface:
thanks for the attention. . .
I hope you can help me:

hi stefano e ciao deran
I would also like to do the same thing....I explain.....I created a .txt file where I wrote all the commands regarding a piezo beam put in vibration by an impulsive force....analyzing with timehist postpro the trend of the voltage, it is (justly) variable over time....I would like to take this variable trend in function in time and insert it as a law of variation of the voltage generator Do I have to create a table of the volt depending on time? How can I do that? ?
Thank you very much
Thank you.
