.dat and .fil file manipulation

Hello to everybody!
First of all, sorry for my english. I would like to remove some data and add another to the .dat file. I know that I have to modify the input file for this, but I have tried to modify the edit keywords adding *PREPRINT...., and I get errors. In the other hand, I would like to create .fil files in order to store data and create graphics. How can I manipulate this binary data?? I´m new in Abaqus and I need your help. Many thanks. __________________________________________________ Correo Yahoo! Espacio para todos tus mensajes, antivirus y antispam ¡gratis!

*.dat output is controlled using *NODE PRINT, *EL PRINT, etc.
*.fil output is controlled using *NODE FILE, *EL FILE, etc. In general, there is no need to depend on *.dat or *.fil output since the primary output database is the *.odb file. Field and history variables are written to this file, and can be retrieved, manipulated, printed, graphed, and contoured in ABAQUS/Viewer. See the documentation for *OUTPUT, *NODE OUTPUT, *ELEMENT OUTPUT, etc. for details. If you're using a third-party postprocessing program, then it may still rely on the *.fil file, but I'd recommend doing your postprocessing in Viewer.

Thank you for the explanation.
The thing is that I have to program a user defined subrutine, which is going to do different simulations changing the model configuration, an I would like to extract data for each simulation. I think that the only way to do that is to store a .fil file in each iteration and then manipulate it with a third-party postprocessing program, otherwise I will be able to see only the last simulation in the viewer. I would like to know how can I manipulate the .fil file, since it is binary information and I don´t have idea about how the information is organised neither how to extract it. Thank you for your help. --- El mié, 28/10/09, Dave Lindeman <ddlindeman@...> escribió: De: Dave Lindeman <ddlindeman@...> Asunto: Re: [Abaqus] .dat and .fil file manipulation Para: Abaqus@...

I'm not sure I understand what you are attempting to do. Is this an
optimization algorithm? If so, run the baseline model, use a Python script to extract the necessary information from the ODB (this can be done in a batch mode), use this as input to your algorithm, generate a new model (with a new jobname), execute the new model, re-run the Python script, etc. -- i.e., create a new ODB file for each analysis. By "user-defined subroutine" do you mean an ABAQUS user-defined subroutine (e.g., DISP), or some external program that will be executing ABAQUS? If you must interact with the *.fil file, see section 5 ("File Output Format") of the ABAQUS User's Manual. The file format is defined, and a sample postprocessing program is shown. Note that it's not trivial to go about creating or modifying a *.fil file.
