PARAVIEW MAKE VIDEO SERIAL

So, serial here means that we loaded the series of CONVERGE post*.h5 files and ran through the animation, creating an image one timestep at a time.įor the HDF5 dataset performance tests, we discovered that processing with Tecplot 360 in minimized memory mode gave the fastest processing time at 1.99 hours, ~5.6 seconds per image. ParaView does not publish a list of which filters are multi-threaded, but “all common filters are ” Figure 1 shows an example of the plot:įigure 3: 360 vs ParaView: Time per Image & Peak RAM Usageįor the generated plot, Tecplot 360 uses multi-threading for a number of operations such as: deriving node-located values from the cell-centered Temperature value (a pre-requisite for iso-surface creation), slice creation, and iso-surface creation. We repeated this for each time step in the data series for a total of 1278 images produced. The goal is to capture the execution time and peak RAM required to create a plot which consists of a slice colored by temperature and an iso-surface of the flame front (temperature = 1700). This dataset is composed of 1278 timesteps, totaling 169Gb on disk. Since many CONVERGE users need to create movies of their results, we chose a reasonably large, multi-cycle internal combustion engine (ICE) simulation. By avoiding running post_convert you’re saving yourself time and disk space. TfC, 360, and ParaView each include a direct data reader for CONVERGE post*.h5 files, which means that with these post-processors there’s no need to run post_convert. batch-processing), the most popular options are Tecplot 360 or ParaView. However, for users who are looking for more power than what TfC offers out of the box (i.e. For today’s post we’ll be diving into performance with CONVERGE data only.ĬONVERGE users are fortunate to have access to ‘Tecplot for CONVERGE’ (TfC) as part of their CONVERGE license. Of course, performance is dependent on several factors – and which data type you are using is an important one. ParaView for CONVERGE DataĪt Tecplot we know that you have choices when it comes to post-processing and that your time is important to you, so we’ve done some performance testing to help you decide which post-processor will perform the best with your data. « Back Which is Faster?
