Exporting pressures

Hi All,

I'm trying to get some pressures out of a feflow simulation, but I'm not understanding the results.

When I go to "Halt and view results" and ask it to show in the screen, I see values up to 6400 kPa, however, when I export the same pressures as a surfer grid, I get maximum values of 1090.

Are the values from the surfer grid  in a different unit, or are they calculated differently?

Regards,

It is hard to find the reason for this without looking at the model... if the grid resolution of the surfer grid is coarse, it might be caused by interpolation.

Hi Peter,

Once again, thanks for the help.
In this model I think that interpolation is probably not the issue, as when I export the heads to surfer grids, they match exactly with the ones from the feflow screen.

After checking that, I also noticed that the surfer grids for pressure and head are exactly the same, so I'm not sure what is going on.

The model is basically a 2d cross section when we are trying to get some pore-pressures. We have rainfall recharge at the bottom and a constant head in the east side to represent the sea, which is mostly and outflow zone.

This seems to be a bug - 'head' and 'pressure' both export head values. I've forwarded this to our developers and will let you know when a patch is available.
