Thank you for your help. the parameters were obtained by suction and permeability tests constant load. But because of the inconsistencies already decided to replace them with what was observed in the field, and this corresponds to a coarse material. the question now is, as income a column of water o...

respose:
1. precipitation = 11.54 m/d

2. theta r = 0.024
Theta s = 0.264
alpha = 5.039 1/m
n = 4.0611
Ks = 0.0864 m/d

3. -0.405
4. En surface, apply Line-FE-Size, S = 1 m, and the rest of domain TS = 5 m

Mirek Thanks for your reply. This happens to me only when I try to put a boundary condition at the top: atmospheric, variable flow, etc. I never had happened, but never had a problem with a domain so long and shallow. I then make the model more profound? or increase the mesh in the upper? Regards,

I tried to increase the spatial discretization, given that my temporal discretization seems like it matched up with the info contained in the link you shared. but i have the same problem. Are you help me??

Hi. I have the version 2.008 of Hydrus-2D. I have the same problem of gloating point error. Mi domain is 4000 x 63 m. I need determing the flow in the domain for precipitation of 1 day. I tried to increase the spatial discretization, given that my temporal discretization seems like it matched up wit...
