<div dir="ltr">Hi Özgür,<div><br></div><div>That's a common error to see when a field is requested that doesn't exist in the file. I believe that "io" typically refers to a particle type. You can get more information by looking at what is listed when you examine the output of "ds.field_list" and "ds.derived_field_list", which should list items by field type and field name. If this doesn't help, please feel free to drop by the yt-users mailing list or slack and we can get you set up.</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Mon, Feb 20, 2023 at 2:07 AM Özgür Culfa <<a href="mailto:ozgurculfa@gmail.com" target="_blank">ozgurculfa@gmail.com</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div dir="ltr"><div>Dear all,</div><div><br></div><div>I am a new user of FLASH and trying to sort out how to do the visualization.
