I have calibrated the groundwater flow model manually. I want to quantify the uncertainty and sensitivity of the model. I'm not able to select post-calibration monte Carlo from the optimisation control window. anyone pls help? thank you.

Hello, is it possible to run feflow using more than one computer to increase simulation speed?
-
why specific yeild is not showing in data panel for 2d vertical model? instead of specific yield, it shows specific storage. I'm trying to model an unconfined aquifer in the coastal region.
-
can i get any reference on how to assign longitudinal dispersivity?
it depends on scale, which means distance from source?
-
Scale means, total with of model? or size of elements. my model area is around 1000km2 area. i should put single dispersion value for entire or increasing disperion value from sea boundary to other side of model?
-
is there any way to simulate air pressure developed wen large amount of water was water was poured in to the tank ?
-
When i gave little high value, the head shows some error during the stress period. why is it so?
-
When i gave residual water level 0.2m model run without any error. Thank you so much
-
if the average water level from the ground is around 5m, what range of value I can apply from residual water level?

model is too slow and the time step is also small When I assign vertical hydraulic conductivity 0.1*kx.
details about the model:
since an urban area well was given throughout study area where buildup is there
recharge was given 10% of monthly average rainfall
model is run under the phreatic condition
study area mainly consists of alternate layers of clay and sand. is there any thumb rule like vertical flow should be 0.1*kx?. Since inflow from the first layer to bottom will b high due to gravity, feflow will consider it automatically? because i think the problem for small time steps is due to slow the vertical flow of rainfall
