what does this verbose error mean?

everything seemd ok but abruptly this long error displayed.

We are back at the same problem, which we discussed some time ago.

Look at dump #4, #5 and #8. You are doing an illegal operation on a value using your pow-function in your groovyBC - recall Bernhard's long list of potential issues.

I guess the rest is merely pyFoam quitting because of the crash.

Good luck,

Niels
