output access

[aclesage]

Dear all

My name is Anne-Cecile Lesage
I am a research scientist at Md Anderson Cancer Center with experience in running an developing finite element codes
I am a new user of febio on windos
I am wondering how to access the results displacements in each node in a format i can read with my own postprocesses analysis codes
so far i am only able to see the results in the febio plots format which is a binary
Maybe i shall look in the source code to see how the febio plot file is written
any guidance for that?

thank you
regards
Anne-Cecile

Hi Anne-Cecile,

There are two approaches you can take:
1) You can write the nodal displacements to a text file, directly from FEBio, using a user-specified formatting. Please check section 3.17.1.1 of the online user's manual.
2) Alternatively, you can export the data from the Data panel, which is a tab on the Post panel. After opening the plot file, find the Post panel, and click the Data tab. Then, select the displacement field in this panel and click Export. You can store the data into a text file.

Please give this a try and let me know if you have any further questions about this.

Cheers,

Steve

Dear Steve

thanks for the quick answer
in my future use, regular use, i will use the first one, i guess for automatization purposes
second one works fine, for each node i ask the displacement
I did the simple example of first run with febio with displacement in x imposed at one face of a box
i get 11 time outputs
the description is for each node
node id, dispxt1, dispyt1, dispzt1, dispxt2, dispyt2, dispzt2, etc ...
right?
regards

Hi Anne-Cecile,

That is indeed correct. The file is formatted as you described.

Cheers,
