The transOrder option is obsolete and should always be =1 in the code. The fact that it even appears in the code anymore is vestigial. I would suggest removing it from your Config file, then resetup without the -noclobber option. It can sometimes cause strange behavior.</div><div class=""><br class=""></div><div class="">Sean</div><div class=""><br class=""></div><div class=""><br class=""><div class="">

It appears that the transverse flux array is not defined for some reason. I've also noticed, oddly, that the "transOrder" option does not appear with the +uhd flag, but only when I include the unit in my Config file, however, adding this unit does not solve the seg fault. When I switch to the unoptimized solver (+uhdold), the code *does* work.
