Hello,

I'm trying to run a Visual Modflow model in RT3Dv2.5 using
Instanteneous aerobic decay of BTEXN. I've put in a constant
concentration for BTEXN and oxygen in one layer. I've tried several
solvers and it gives no problems during calculation. However, I never
get a concentration value in my output. Can anyone help me with this
problem?

Regards,
