RE: [EnergyPlus_Support] Re: SVG Flow Chart and Nodes

I cannot comment more without looking at the IDF.

If you were using templates for IDF generaton, send me the template version as well.

The first error or warning message will generally tell you what you have done wrong.

Hundreds of warnings may follow with just one error.

The only change I made from a run with 0 errors and 0 warnings to one with a lot of node erros was changing the CFM rate of a supply fan from 5,000 CFM to autosize.

This can cause errors?

If you are changing the number using a text editor or IDFeditor, you may have changed some other objects or the order of a branch. For example, if you deleted a branch object and insert a new object with your changed field, the order in the file is changed. IDFeditor can only append and not insert. This is one possible way to generate connection errors. There are other possibilities, such as an extra comma in the object. When you first intriduce autosize in your IDF, you may be asked for a sizing object or to do sizing run. Dr. Li

But the order of these listing may not be the same as those in the SVG diagram as there are coordinates associated with these captions to draw them. The .bnd listing follows your IDF ordering. Dr. Li
