Before Starting

Make sure you have your Phasta restarts and a copy of ParaView. This tutorial was made using Paraview version 1.2. The ENSA reader is able to read restart files from Phasta 1.9.

Reading ENSA Results

Creating Meta File

Before using ParaView to visualize your data, you must create a meta file. The meta file tells ParaView where your geometry and solution files are located as well as how many partitions of data. The meta file that you create must have an .ensa extention.

Example Meta File:


GEOME specifies where the geometriy files are located, FIELD specifies where the solution files are located, NUMPI specifies how many pieces the data was partitioned into, and TIMED specifies if there is time step support or not.


  • Launch ParaView
  • Go to File > Open Data. Select your ENSA result.
  • Apply Filters to your result.


(To Do)



The contour filter computes isolines or isosurfaces using a selected value.


The cut filter extacts a portion of the data that lies along a specified plane or sphere.

Applying Filters

Making Vectors

Make sure the scalar quantity is in front of the unit vector. If the unit vector is placed in front of the scalar quantity in the muliplication, it will cause the value to always be 1.

Creating Isosurfaces

An isosurface represents a surface drawn consisting of points of a constant value within a volume of space.

  • Apply Calculator filter by going to Filter > Calculator.
  • Enter equation that you wish to solve for into the calculator and click Accept.
  • Go to Filter > Contour.
  • Go to the Display tab and make sure the Color by: is set to Point Result
  • Click Edit Color Map...'.
  • Change the Resolution. This sets the number of different colors in the color map.
  • Click Reset Range and then click Back.
  • Go to the Parameters tab and add values that you would like to generate an isosurface for. You may also generate a range of values here, or delete values you do not wish to use.
  • Click Accept when you are done. This should generate your isosurface.

Displaying Velocity Vectors

  • Apply Calculator filter by going to Filter > Calculator.
  • Enter vector that you wish to solve for into the calculator and click Accept.
  • Go to Filter > Glyph.
  • Select your representation of the vector in the Glyph drop-down box.
  • Change the Max. Number of Glyphs to the max number of glyphs you would like to display.
  • Click Accept.

Creating Streamlines

  • Apply Calculator filter by going to Filter > Calculator.
  • Create a velocity vector.
  • Click Accept.
  • Go to Filter > Streamtracer.
  • Change the Seed to either Point Cloud or Line.
  • Click Accept.
  • Highlight the stream in the selection window.
  • Go to Filter > Tubes or Filter > Ribbons.
  • Adjust parameters and click Accept.
