Hi Christof,

I use 2.0 master, and last build was on 8/28/2018.

We re-built to use the new mask feature.

Should I try doing a fresh build?

Thanks,

Nicole

Hi All,

I'm getting the following error when running the GA:

Evaluation of objectives or constraints threw an exception!

Is there any way for me to find out which obj or const. is giving the exception?

I'm running with --info 5, and I suspect the following constraint:

c4: CONSTRAINT, EXPR="fabs(statVariableAt('numParticles', 19.4))>95000";

Or maybe my syntax is wrong?

Thanks,

Nicole
