Richard, Did you click the "Apply" button after entering the expression in the calculator filter? After you click the Apply button ParaView will evaluate your expression on all elements of your data.
The new variable becomes part of the newly generated data set labeled as "Calculator1" or something similar in the pipeline browser (at the left of the GUI). The variable is available when showing that data in the view or adding subsequent filters to that. If this talk of filters is confusing, I suggest taking a look at the ParaView tutorial (http://www.paraview.org/Wiki/The_ParaView_Tutorial) and/or the ParaView guide as Utkarsh suggested earlier to learn the fundamental concepts of ParaView. -Ken From: <Rinehart>, "Inc.]" <richard.d.rineh...@nasa.gov<mailto:richard.d.rineh...@nasa.gov>> Date: Monday, February 9, 2015 at 8:51 AM To: "paraview@paraview.org<mailto:paraview@paraview.org>" <paraview@paraview.org<mailto:paraview@paraview.org>> Subject: [EXTERNAL] [Paraview] Defining new Variables Greetings! A relative newbie Paraview question[http://www.cfd-online.com/Forums/images/smilies/smile.gif]. In Ensight I use the calculator to define essentially a new variable, such as degrees F as computed from K. I've done that in Paraview but it doesn't seem to then be available to use. ?
