Non-selected node affects end-results
Posted Oct 25, 2013, 12:53 PM EDT Parameters, Variables, & Functions Version 4.3a 4 Replies
I have various physics nodes in one single project. (Both are Transport of Diluted Species nodes.) One of them works with a variable "n" and another "h". I also have a Study, with a Step which is Time Dependent. Here, in "Physics and Variables Selection", I only select one of the two nodes (let's say, with output "n"). However, when I plot out the results (i.e variable "n"), these seem to be influenced by both nodes. When I only plot "h", I get 0, as it should be.
When I disable the second node (the one with "h"), and redo the study, then the result, plotting "n" is as expected.
In other words: the "n" result depends on whether or not the "h"-node is enabled, even though the "h-node" is not included in the time-dependent Study Step (nor in any other Study Step)! How is this possible?
Why does a node influence my result, even when the node it is not selected in the Study section?
P.D. (I have COMSOL multiphysics 4.3a)
