We have answered the questions we needed and could have added the code if the need to use paraview was urgent. Of course, this whole exercise (about an hour including download) demonstrates the wisdom of using open source in a research/teaching environment. I could have greped to see what uses the new class but I had pretty much established paraview still cannot do what we want and we are better off sticking with visit and waiting for parview to evolve a bit more.
However, ensights format may not need something extra it in order to define multiblocks. I did not look at the ensight code but there is no specific reader for multiblock unlike the other two formats. The parameters I would expect to see were not in evidence.
#Tecplot download how to#
There is an example of how to write some C++ code to get multiblock into vtk but how well supported the connectivity and handling of ghost cells is I do not know. Multiblock has started being added to the native vtk file format but is incomplete with most of the functions being empty in the reader. Multiblock is in the Plot3D reader but the Plot3D reader is only partially implemented and it will only read velocity and 2 thermo properties and not other variables like acoustic, electric and magnetic fields, species, etc. There was a note about missing functionality but I did not understand the vtk-speak to appreciate what it was. They have added a new class to the guts of vtk which presumably handles multiblocks although I did not read it to find out what (no documentation and C++ inheritance makes browsing someone elses code structure very hard work). I downloaded and installed the latest stable version, read the source code and it has only partial support for multi block grids. Tecplot realy seems to be powerful but I was not able to use it.
#Tecplot download software#
I tried Tecplot some time ago but the first few minutes with a software are enough, for me, determine if this software is easy or hard (for me again) to use and I ended giving up. The same file that is read by Ensight and Paraview, VISIT is not able to read and I can't figure out why yet. I'm still trying to read my Ensight case files in it without any success yet.
For example: the multi-block reader was just implemented in version 2.4.x. Ensight, for me, is the easiest file format I've ever faced with.Īnother issue that must be considered is that Paraview has been frequently developed and most of the "desired" features were not implemented/tested yet. File format: Paraview give you support for at least 30 file formats, including some famous formats such as: Ensight, Plot3D, HDF5, etc. You just put your question and wait a few minutes to get your answer Support: I think that Paraview's mailing list is much more userful/helpful than any other kind of support. Version 2.4.x of Paraview supports multi-blocks structured and unstructured I began to use Paraview only using a short description of the software and I thought the software so easy to work that any book was necessary to learn the main features. Well, you don't need to buy Paraview's books to start using it. Paraview has a bit more plotting capability but the better file type support (for our uses) and documentation of visit currently gives it the edge for our purposes. This is encouraging for the future at least until support for one or both the projects gets axed which happened to paraview for a year or two. Anyone know of such a reader? There is no documentation available for paraview until "early 2006" whenever that may be.Īlthough the commercial software is still better for student use both these programs have evolved from poorish a few years ago to really quite usable today. They have different strengths and weaknesses but, extraordinarily, paraview does not seem to support multi block structured grids and we are not going to write such software for it without documentation. The choice was effectively between paraview and visit and we opted to stick with the latter although we will support both eventually. We have recently looked at 3D plotters but commercial programs like fieldview and tecplot are not viable because of the cost (impoverished university requiring lots of copies on a range of platforms). As dpshaka says, tecplot is commercial software and paraview is freeish (ish because you need to spend about 150 euros on a couple of books to get the documentation).
