If this is not desired, change the value to 0.5. Note that since we will have two materials touching each other, our default Volume Fraction Value will have some cells visible on top of each other.This means that ParaView will store volume fractions as an unsigned byte. Notice the Down Convert Volume Fraction has been checked.Markers are groups of points that move with a material.Tracers are points in the mesh that move with a material, and can include variable information.Volume data is the structured data from the CTH simuliation.There are three types of data that have been read in.Our goal is to create a contour where Material Volume Fractions is at 10%. Generally, you want a surface (contour or clip by scalar) at about 10%.Ĭreating contours with the Extract CTH Parts filter ParaView reads these into unsigned bytes, which range from 0 to 255.

These are actually stored in the files as floats (4 bytes) or doubles (8 bytes). All material volume arrays go from 0 (representing 0%) to 1 (representing 100%). ParaView reads spcth files in an very efficient manor.

This tutorial assumes that the user is already farmiliar with ParaView.

They can be flat mesh or adaptive mesh refinement (i.e., AMR). CTH Spyplot files are Eulerian, or structured mesh datasets.

CTH is a multi-material, large deformation, strong shock wave, solid mechanics code developed at Sandia National Laboratories.

This tutorial shows how to visualize CTH datasets (called spcth files). 5 Analyzing fragments with the Material Interface filter.4 Creating a filled isovolume with the Clip by Scalar filter.3 Creating contours with the Extract CTH Parts filter.Department of Energy’s National Nuclear Security Administration under contract DE-NA-0003525. Sandia National Laboratories is a multi-mission laboratory managed and operated by National Technology and Engineering Solutions of Sandia, LLC., a wholly owned subsidiary of Honeywell International, Inc., for the U.S. Note - there seems to be a bug in ParaView, where if you click on the Contour filter again, it will ask you to apply.In the pipeline browser, I also turned off visibility for the Contour filter. Change the pulldown box next to the blue + to be Contour.Optional - I increased the scale factor by about 5X. Turn all variables on, and hit the apply button. We will also add glyphs to the streamline points. Our goal is to create a set of streamlines from a vector field, place points on this set of streamlines, and animate the point down the streamlines.If you have a vector field in your data, you can animate a static dataset.Change Backface Style - Representation to Cull Backface.Slide down a few pages until you find Backface Style. It is possible to change the backface style of a wire frame object.Turn visibility of can.ex2 on, and Representation of Wireframe.Choose Scalars of “Quality”, and Lower Threshold of 4 and Upper Threshold of 1000.Next, we want to only look at those cells that are below some threshold of quality.Filters → Alphabetical → Mesh Quality.Mesh quality is created using the Mesh Quality filter.For instance, this example will create a vector representing the acceleration in the X and Y plane. Build the vector equation using the iHat, jHat and kHat buttons on the calculator.To see the ranges of these variables over the whole mesh, look in the Information tab.You can now visually see average acceleration, maximum acceleration and average displacement of each cell. Filters → Temporal → Temporal Statistics.We now have a ClipByScalar filter (sometimes incorrectly know as an IsoVolume filter). Turn Scalars to Temp, enter a Value of 400, and hit Apply. Open Filters/ Alphabetical/ ClipByScalar.Now, delete the clip filter in the pipeline browser.Select the clip (in the left window), and pull down the pull down menu for Property.Name this filter ClipByScalar (IsoVolume).From the Tools menu, select Create Custom Filter.(The Scalars and Values don’t matter right now) On the Display tab, select Color by Temp. On the Properties tab, select all variables and press the Apply button. This wiki page holds tips and tricks that don't fit anywhere else, or are small enough that they don't deserve their own tutorial.
