How to debug a problem

[rpuenter]

I´m trying to use this utility with my mesh, but it fails at the domain redimensioning stage. With some put statements I find that the probelm is that in lines 582-587 (copied below), domMinEdgeLen and domMaxEdgeLen are set to Automatic instead of to a number. Then lines 592 or 596 will fail because it is expecting a number. I´m not familiar with Glyph, is there a reasonably easy way to fix this issue? I guess it´s a matter of consifering also the "Automatic" case in the logic, but I lack the knowledge to implement it.

# Refine interior triangles of unstructured domains if necessary. Do not refine
# diagonalized domains, they will be regenerated
if { [$dom isOfType "pw::DomainUnstructured"] &&
     [array get diagDomNameToOrigDom $dom] eq "" } {
  set domMinEdgeLen [$dom getUnstructuredSolverAttribute EdgeMinimumLength]
  set domMaxEdgeLen [$dom getUnstructuredSolverAttribute EdgeMaximumLength]
