Re: [Paraview] FEM solver interfaced with Paraview
of the following questions have probably ever been asked, but: 1. What is the best format to create a result file readable by Paraview, especially for huge file? after some readings, VTK XML format seems to be the most interesting (parallelization capabilities) compared to the legacy VTK one, am I right or do ou have any other suggestion? 2. I’m still trying to figure out if xdmf and/or hdf5 format are relevant, and if they are relevant for my application: any feedback on it? The workflow I’m imaginating sounds like: Intermediate calculations Raw data (ascii file) from my solver --> intermediate file in xdmf or hdf5 format --> Paraview input file (depending on the reader) To my understanding there is no xdmf OR hdf5: http://xdmf.org/index.php/Main_Page We also have an own FEM Code. We export directly hdf5 files (w/o xdmf) which we read with an own paraview reader plugin. Now we would probably try xdmf and see if we can circumvent having an own reader plugin. hdf5 has libs for all languages (C/C++, Python, Matlab) and e.g. the handling in Python is quite convenient. Almost a one-liner. The hdf5 C/C++ lib for writing the data is not the best software I know but it is ok. I would not export to ascii first but directly use the hdf5 libs.

[Paraview] FEM solver interfaced with Paraview
Dear all, A while ago, I've initiated an internal project to export results from my Finite Element solver (mechanical and thermal FEA's) and to visualize it into Paraview (https://www.paraview.org/pipermail/paraview/2017-November/041481.html); but I was quite overloaded and this topic has been postponed. Currently the format of my the solver is not a part of the list (https://www.paraview.org/Wiki/ParaView/Users_Guide/List_of_readers), and I'm thinking about the strategy to get the results, to perform additional calculations, and finally to post-process it into Paraview. _Nota_: I'm using 2D and 3D meshes, structures and unstructured ones, with different element orders, and different type of results (nodal values and/or cell ones). Some of the following questions have probably ever been asked, but: * What is the best format to create a result file readable by Paraview, especially for huge file? after some readings, VTK XML format seems to be the most interesting (parallelization capabilities) compared to the legacy VTK one, am I right or do ou have any other suggestion? * I'm still trying to figure out if xdmf and/or hdf5 format are relevant, and if they are relevant for my application: any feedback on it? The workflow I'm imaginating sounds like: Intermediate calculations ^ | Raw data (ascii file) from my solver --> intermediate file in xdmf or hdf5 format --> Paraview input file (depending on the reader) Any feedback, advice and suggestion will be highly appreciated (I'm quite new with Paraview) Regards Paul___ Powered by www.kitware.com Visit other Kitware open-source projects at http://www.kitware.com/opensource/opensource.html Please keep messages on-topic and check the ParaView Wiki at: http://paraview.org/Wiki/ParaView Search the list archives at: http://markmail.org/search/?q=ParaView Follow this link to subscribe/unsubscribe: https://paraview.org/mailman/listinfo/paraview
