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.
Numerical convergence problem
Re: Numerical convergence problem
Since the Richards equation is a highly nonlinear equation, there is always a chance that the numerical solution will not converge. However, for physically realistic problems, this should be rather rate. J.
Re: Numerical convergence problem
Dear Sir,
My issue is not with the nonconvergence 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

Re: Numerical convergence problem
I would need to see your project. However, I would not have time to look at it until the end of September as I’m currently traveling in Himachal Pradesh, India. J.
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.

Dear Sir,
Please check this attachment, in the earlier attachment forgot to add some files.

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,
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.
