Automated Textfile Export of History Output Requests of all opened ODB Files in current CAE session

Hi there,
This plug-in (

http://www.eng-tips.com/viewthread.cfm?qid=385460)

collects the data from the History Output and generates an excel file. Does anyone know how to re-write the plug-in in order to sum the loads over a surface in the History Output?

Thank you!

I can't see what your task has to do with the mentioned plugin. This plugin just takes the history output and writes in text files. What you want to do is very different.

What loads do you want to sum (CF? RF? ...)?
Is this variable available as field output and/or history output?


I've a script that sums RF (magnitude and components) for the regions that are displayed in the viewport. It would be easy to change it to do the same with CF.

Thanks for your reply!

I would like to sum 'RF2' over a surface. Have you made available any script?

Cheers!

It should be attached to this post.

Open it with an editor to read the instructions.

Thank you!

The script is running well but it only gives the final sum of 'RF-2'. In fact, I would need the sum of 'RF-2's over a surface at each time increment. The plug-in I've been using only gives me 'RF-2' of 1 node at each time increment and that is the problem. Please, would you have any thoughts on how I could solve that?

Cheers!

This is a picture of the model I've been working on. As you can see, I'm applying a displacement on the top of the sphere and I'm willing to compute the sum of 'RF-2' (on the top) as a function of the displacement (U2).

Cheers!

1. You can change the script to get the data in each output frame and write it in a txt file.
2. Maybe you can couple the face to reference node and apply the displacement there. Then you can get the curve directly as history output for that node.
