Seems like the equation parser is not recognizing most of the variables and constants. Using 2.19.17 beta on ARM MAC.
Thanks for letting us know.
I’ve deleted 2.9.17 as it’s a major bug.
CERN is closed now, I’ll fix next week when everyone’s back from holidays.
It looks like the bug only appeared on the Mac ARM version, even though it was a logical error.
I’ve released Molflow 2.9.18 with the fix, click About/Check for updates to get 2.9.18, with the formulas working again.
Thanks again for the report.
