<div dir="ltr"><div><div><div><div>Hi Cornelis,<br><br></div><div>How would you like to select the single or group of values to change? Also, how would you like to change them (e.g. the same transformation for each or each with its own transformation)? These two questions are meant to guide you to do what you want in ParaView.<br></div><div><br></div>You probably want to look at the Python Programmable Filter (<a href="http://www.paraview.org/Wiki/Python_Programmable_Filter">http://www.paraview.org/Wiki/Python_Programmable_Filter</a>) for changing individual array values. If you are working in serial you may also be able to bring in the entities to change based on a selection. A better solution would be to use the global ids filter, then do a selection on what you want and finally pass that in as a secondary input to the Python Programmable filter. <br><br></div>Developing your own filter is also a possibility.<br><br></div>cheers,<br></div>Andy<br></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Jan 17, 2017 at 1:38 AM, Cornelis Bockemühl <span dir="ltr"><<a href="mailto:cornelis.bockemuehl@gmail.com" target="_blank">cornelis.bockemuehl@gmail.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div dir="ltr">Dear Andy,<div><br></div><div>Thanks for this hint: Indeed I was not fully aware of the way how you can easily add new calculated columns with these two filters!
