I have noticed very large flow imbalance errors occurring in my model when using the Phreatic method of simulating confined/unconfined conditions. Changing the top slice to "Free" improves the imbalance but degrades the model's ability to represent large vertical head gradients observed in the calibration data. I would rather use Phreatic mode for this reason as it enables the best calibration to heads and outflows.

Are there any known issues with imbalances while using the Phreatic mode? Are there any work arounds?

I have tried refinement around wells and this doesn't help. The imbalance errors are greatest when well BC abstraction is occurring.

It is a 5 layer regional scale transient flow model.

Thanks in advance...

Agree - I've made this comment in the past.

Many of us use output files for post-processing and the formats exported from FEFLOW are unnecessarily difficult to work with. Please can there be a tab or comma delimited output option? This applies to POW files too!

I ended up finding VS Express 2013 and looks like it does the job.

I have moved company and want to re-start IFM programming. Previously, I used MS Visual C++ 2010 Express Edition (free). This no longer seems to be available for download.

Can anyone suggest what the best (free) option is now? A link would be even better!!

Thanks in advance...
