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
