Re: [opendx-users] Include/replace question

[Chris Pelkie]

This stuff gets tricky sometimes, because if there are existing 'invalids' some operations, like Replace, may not necessarily cleanly overwrite stuff that is seen as 'invalid'. I would try Remove(invalid connections) followed by Replace(new invalid connections).

I have two fields (connection dependent data) over the same unstructured
tetrahedral mesh. One field is my real field, and the other has integer
valued data that marks the different subdomains (materials). What I'd
like to do is to ShowBoundary of the real field over one (or more) of
the subdomains. To do this I use Include on the 'material' field to
pick out the subdomain I want (this works), and then use Replace to
substitute its 'invalid connections' component for the 'invalid
connections' component of the real field, before sending it to
ShowBoundary. I get no errors or warnings, but it seems to have
absolutely no effect. What am I doing wrong here? Is there a better
way to get what I'm after?

Thanks!
