<html><head></head><body style="font-family: times new roman,new york,times,serif; font-size: 12pt;">Dear Paraview users,<br><br>we are planing to use Paraview for our calculations and i've done some research on the availible file formats. But there are some points I do not understand or i can't find any Informations on it. I hope one of you had similar questions and might help me now.<br><br>There are several things we want to do and i'am not sure which file format is the right one for us:<br><br>1. We want to animate our results, meaning we have datas for every time step and want to make an animation out of this.<br><br>Problem: Vtk File format can do this, but as I see it, you need an extra file for every time step.As If we are having about >10000 timesteps this is getting a bit cumbersome. Is that right or is there a way to put all the datas in one file? <br>As an alternativ there is the xdmf file format, there i already figuered out a way to put all the time step datas in one file. But the Problem is:<br><br>2. We want to use the facility of Coprocessing, meaning we want to see our results just in time during the simulation.<br><br>Problem: As I understood the ParaView User Guide this is only possible with the vtk File Format or is there an "easy" way to realise this with the xdmf Format?<br><br>Last but not least we want to use existing libarys to write our datas with C or C++.<br><br>Regards,<br>Claudio<br><br><br></body></html>
