ParaView Tutorial

Contents

ParaView is an open-source, multi-platform data analysis and visualization application. It is the primary post-processing tool for ParaGeo 2D and 3D models. It can be downloaded from https://www.paraview.org/download/

This manual chapter is focused on describing how to perform the most used processing operations for geological problems in ParaView.

At the bottom of this page we have a Quick Reference Sheet with short descriptions of most useful filters and functions. Furthermore Filter names may be clicked to navigate to their corresponding detailed usage description pages.

In addition a "Quick Example Tutorial" is included. This will use results provided in ParaView_001\Results folder and guide you step by step on most commonly used processing operations in 3D geological problems.

For more detailed information about ParaView tools and usage we may visit the following page: https://www.paraview.org/Wiki/ParaView .

Quick Reference Sheet

FILTERS
Calculator		Calculate new variables from mathematical operations of existing state variables. They can be based on point (nodal) data or cell (element) data.
Cell data to point data		Calculate nodal averaged values from element state variables.
Clip		Defines a plane by its normal vector which is used to cut the model so that the part of the model in the opposite vector direction is no longer visible.
Extract block		Extracts data by a selection of either/both groups or contact surfaces so only those selected will be visible
Glyph		Generates a glyph of the selected vectorial variable (e.g. contact stress vector, flow vectors, etc.) at each point of the domain (or each N points)
Plot Over Line		Generates a graph of all state variables on a user defined line (i.e. in a straight well path manner)
Plot Selection Over Time		Generates a graph of the evolution of all state variables statistics with time for selected points and/or cells
Probe Location		When selected it allows to put a probe at cursor location and return the coordinates by clicking Ctrl+P
Slice		Defines a plane by its normal vector which is used to cut a slice of the model.
Threshold		Defines a range for any point/cell state variable so that only those points/cells within that range are shown.
Transform		Translates, rotates and or scales any dimension of the model by an user specified amount
Warp by Vector		Translates the points of the input dataset a user specified distance using vector data
FUNCTIONS
Show/Hide data		Shows or hides the selected data (which is nearby the eye icon in the pipeline browser)
Select contour plot variable		Selects the state variable to be plotted as a contour plot. Note that variables with the icon are element variables whereas variables with the icon are nodal averaged variables.
Show/Hide legend		Shows or hide the legend in the contour plot window
Show colour map editor		Shows the colour map editor from which we can: •Select the colour scale preset •Modify the colour scale preset •Modify the legend appearance
Rescale to data range		Rescales the colour scale to the data range from the minimum to the maximum values for the active state variable
Rescale to custom range		Rescales the colour scale to a user defined range for the active state variable
Reset camera		Resets the camera so that all visible data can be seen on the screen
Zoom to data		Adjust the camera position and zoom so that the selected data (e.g. a slice of the model) is shown on the screen
Zoom to box		Does a zoom to the box defined with a mouse click
Set view direction perpendicular to an axis		Sets the screen view to be perpendicular to the selected axis in either positive or negative directions (this will depend on the icon chosen)
Show/Hide axis system		Shows/hides the global axis system orientation at the bottom left corner of the contour plot window
3D / 2D mouse behaviour toggle		Changes the click and drag mouse behaviour for the contour plot screen view. When 2D is active the click and drag mouse results in camera translation. When 3D is active the click and drag mouse results in camera rotation.
Select cells ON		When activated allows to select cells by left clicking and dragging the mouse to define a selection box. Selected cells will be those which are partially or completely within the selection box.
Select points ON		When activated allows to select points by left clicking and dragging the mouse to define a selection box.
Select cells through		When activated allows to select cells by left clicking and dragging the mouse to define a selection box. Selected cells will be those which are partially or completely within the selection box plus all of those which are in the perpendicular projection of the current view (e.g. inner cells within the selection box).
Select points through		When activated allows to select points by left clicking and dragging the mouse to define a selection box. Selected points will be those which are within the selection box plus all of those which are in the perpendicular projection of the current view (e.g. inner points within the selection box).
Add extra layout		Adds an extra layout for which any type of view (e.g. Render View, SpreadSheet View, etc) can be selected.
Split render view window vertically / horizontally		Splits the render view window either vertically or horizontally so that different data (or different views of the same data) can be simultaneously visualized
Maximize the selected view		Maximizes the selected render view window from an split screen
Restore split render view		Restores an split view after a render view window has been maximized
Delete render view window		Deletes the selected render view for which the icon is clicked.
