Re: Time step

Professor Jirka, I have change the time settings as suggested but the cumQ results still change depending on the print options, more specifically if the t-level information is selected. Would you mind to have a look at the case? I am not sure what can be the mistake Thanks, LP https://www.dropbox.co...

Time step

Dear all, I am still learning how to use HYDRUS and I have some doubts about how the time is discretised. More specifically about how does the T-level information option affects the discretisation. From the manual I understood that the numerical time step, the time step indicated in the BC, the time...

Re: Drain outflow simulation

I have created a meshline following the steps explained on a previous post. However, I can't select the option of calculating fluxes across the meshline. I have a change of soil properties in those points too. Does it interfere in any way?

thanks,

LP

Re: Drain outflow simulation

Thank you for your previous answer Professor,

In case I have the same type of boundary condition over several surfaces. Could it be possible to obtain the results at the boundaries individually?(e.g. water that flows in to the pipes and water that recharges the water table).

Thank you,

Error reading results

Hi all, I am simulating a flume test full of railway ballast in order to determine the Van Genuchten parameters. At the moment I am assuming that the ballast is similar to the gravels and use parameter from the literature. However, there seems to be a problem with the input parameters, it says error...

Drain outflow simulation

Hello, I am a new HYDRUS user and I am modelling a 3D railway drainage, which is composed by a perforated pipes and different layers of sand and ballast that act as a drainage materials. I settled up an atmospheric boundary condition at the top, no flow at the bottom and at the sides of the domain, ...
