question

Hi,

The problem seems to be that in the statistics part of the loading arm's tree, there are both old-style nodes that get converted to a kinetic tracked variable, as well as new-style kinetic tracked variables, which leads to two nodes both trying to track the input:

For some reason FlexSim only gets confused when the model stops, and suddenly starts looking at the other one.

This is a problem that already occurs when creating a Loading Arm so I will fix it in the next bug fix release. For the time being, you can fix it by removing the old-style nodes manually:

Thanks for catching and apologies for the inconvenience!

If you have many loading arms in the model already, you could run the following FlexScript from a Script window to try and fix them all in one go:

forobjecttreeunder(model()) {
	if(isclasstype(a, "FloWorks::LoadingArm")) {
		treenode old_stat = stats(a).first;
		while(objectexists(old_stat) && old_stat.name != "state_current") {
			treenode remove = old_stat;
			old_stat = old_stat.next;
			remove.destroy();
		}
	}
}
