Re: Numerical convergence problem

Dear Sir,

Sorry for bothering you. But, is there a way to stop the simulation automatically when there is a NaN value. I mean in the code itself, if there is a NaN value, the code will detect the NaN and stops automatically.

Re: Numerical convergence problem

Dear Sir,

It is happening for energy balance boundary condition only. For Penmann-Monteith equation it is working fine, that is after non-convergence it is automatically stopping. But in my work I am using energy balance BC, so want the simulation to stop after non-convergence.

Re: Numerical convergence problem

Dear Sir, I have attached the screen shot of the simulation runs of two settings. One with max no of iterations=10 and other with max no of iterations=3. when I choose max no of iterations=10, the simulation is not stopping after convergence issue, but with the option max no of iterations=3, after c...

Re: Numerical convergence problem

Dear Sir, The problem still persists. The issue is, if the solution is not converged it should stop, but in my case it is going into infinite loop with all NaN values. Please help me fixing the issue. In the attachments, I have enclosed the project with name daily and also my executable. As an examp...

Re: Numerical convergence problem

Dear Sir,

Issue is resolved. Actually the problem was with hCritA, as I fixed the hCritA to 15000 and for n=1.05 h values are around 10e+20.

Re: Numerical convergence problem

Dear Sir,

what I realized is when the head is less than -10000000 the above problem arises i.e. hydrus doesnot stop after showing the error. Don't know how to tackle this issue.

Re: Numerical convergence problem

Dear Sir,

I have attached my project, please check it. And have a happy stay in INDIA. If you have time do please visit IISc Bangalore. I am doing PhD under prof. Sekhar Muddu in IISc. I guess you visited IISc long back for a short course on HYDRUS.

Re: How to eliminate crashes in batch runs

Hi Mike,

I am also facing the same problem. Sometimes during non-convergence, program is not stopping on it's own can you please help me with that.

Re: Numerical convergence problem

Dear Sir,

My issue is not with the non-convergence of the simulation, the problem is sometimes it does not stops on its own after showing the error, I need to forced stop it. I am attaching the image which shows the problem I am facing.

Thank you

Numerical convergence problem

Dear Sir,

Sometimes HYDRUS does not stop on its own after showing the error i.e. numerical solution not converged! even if I have not checked the option Hit enter at the end. Please help me regarding this issue.

Thermal conductivity in output file

Dear Sir,

In Nod_Inf.out file hydraulic conductivity is available nodewise but I do not see thermal conductivity values anywhere.

large no of print times are not allowed in Hydrus

Dear Sir, I am using Hydrus-1D version 4. I am running the Hydrus for 6000 hours using hourly meteorological data for coupled water and heat transport. I am interested in plotting full profile soil moisture and soil temperature each hour. But in the dialog box more than 250 print times is not allowe...

number of soil materials

Dear Sir, There is no mention of material distribution in any of the input files. For example: I chose two soil materials, my soil depth is 100 cm, fist soil is 0-20cm and the second soil is 21-100cm. In input file there is only mention of no. of materials not regarding the distribution. Can it only...
