Alejandro,<br>
<br>
I agree with you about repeating information.<br>
<br>
I don't think the VTK xml format can do what you're looking for. The exodus format may work for you -- but that may depend upon the type of analysis you are doing. I know that exodus works well for structural, thermal and perhaps some other kinds of physics. There are also definitely people who are far more knowledgeable on this topic than me.<br>

Subject: [vtkusers] file format for transient analysis<br>
<br>
Hi everybody,<br>
<br>
I have the following issue, and no matter how much I search the internet, I can't find an answer for it. I used to work with static analysis, so writing an unstructured grid file worked like a charm for me. However, now I'm doing transient analysis. My first approach was to write unstructured grid files for each of the time steps, and this works well. The thing is that it doesn't make much sense to repeat the information about the mesh in every single time step. Thus, can anyone point me in the direction of the right file format to use? I need a file format where the information of the mesh is given only once, and each subsequent file just gives information about the results (displacements, stresses, etc.).<br>
<br>
Thank you all,<br>
<br>
Alejandro M. Aragón<br>
