Hello all

After a five-year absence, I'm back using FEFLOW. Not only that, I'm attempting to use FePEST.

On my very first attempt, I've run into a problem that I can't figure out.

It's a simple model. I'm trying to estimate six parameters of a 2D, vertical slice, steady-state model. Six Kmax zones and six anisotropy ratios. I've gone through the setup and the checks and everything seems OK but when I run the model, I get the following error messages:

Error condition prevents continued PEST execution:-

Cannot open model output file n1_0032p.fpo.
[ERROR] File not readable: '[path]\FEM\femdata\N1_0032P\n1_0032p.fpi'

When I look in the model folder, I see that the .fpo file does not exist, however, the .fpi file does exist and has the following contents:

Any suggestions?
