Thank you Carlos for your answer,<br> I did not set the&#160;min./max. hydraulic-head constraint correctly and it works fine now.<br> <br> Matan

<p>Hello, I am using a 2D unsaturated model with the pFreeze plug-in. I use a time series of fluid flow as upper boundary condition. While runnung, the model hydraulic head values reach unreasonably high and low head values (~ 1e-9 m).&#160;It is probably a bug that is related to the pFreeze plug-in. As a way around it, is there a way to constrain min/max head values in all the model nodes?&amp;amp;lt;/strong&amp;amp;gt; I tried aplying a min/max boundary condition to all nodes, and also an 'if, else, end' condition in the 'Current expression'. Nothing works. Does anyone have an idea how to limit the min/max range of hyd' head in all nodes?&#160;Thanks in adnance,&#160;Matan.</p>

Hello,
I want to create a time rainfall time series and use it as a boundary condition in a 2D model. I have a few questions:
1) what would be the righ unit clas to use? velosity [m/d] volume [m3]?
2) The value of hydraulic conductivity I use is low, so actual infiltration rate will be much lower then the rainfall rate. What happens to the runoff in the model?

Thanks in advanced,
Matan
