Iteration criteria

Post by hama » Tue Mar 28, 2017 11:06 am

Hello guys,

Can I change the upper limit of the tension interval value from 10000 to 100,000 [cm] in the iteration criteria section ?
if I change it, does it affect the accuracy of the simulation ?

Your reply is much appreciated !

It should not have any noticeable impact. Is there any reason why you would want to do that? J.

Hi Jirka ,
Many thanks for your reply.
I previously emailed you with regard to my project. There is a problem in my work, I can not find it out !
The simulation was run for 240 hours, the field was irrigated for about 4 hours with the emitter discharge 2.5 L/ hr .
Volumetric moisture content of lower and upper parts of the soil profile were 0.23 and 0.11 which are not compatible with the tension interval .
Please see the attachments

Kind regards,
Hadi H.

I ran your project, which did OK. However, frankly, I do not see any question in your posting. J.
