Re: HYDRUS 1D Model Fails to Converge

Dear professor Jirka, Thank you very much for the reply! Actually I tried, but I got two different output in the end (as shown in the Fig.1 and Fig.2). I ran HYDRUS 1D with a single layer as the reference case. I added Alfa2 , n2, but set w2 =0 in the SELECTOR.IN file, and ran HYDRUS again with all ...

Re: HYDRUS 1D Model Fails to Converge

Yes. You can set up dual-porosity model for all layers and then simply make the mass transfer equal to zero, to convert it (in any layer) to a single-porosity model. J. I have a question similar to this.. Will a dual-porosity model work like a single porosity model if I set w2 for the second soil t...

Re: Run Hydrus-1D on Linux

Dear all, I compiled HYDRUS 1D on an Unix system and tried to run a simple case (only with precipitation as upper BD and free dranage for bottom BD). But in the end there showed some error message 'Floating Point exception' like the picture below. Hydrus.PNG I was calculating the moisture profile fo...

Re: Recommended Compilers

Hi all, I have a question about compiling the source code. I am new to FORTRAN. I read the document 'comment out) in the main file calls to functions GetDat and GeTim', I saw the code call getdat(iYear,iMonth,iDay) call gettim(iHours,iMins,iSecs,i100th)' But there is another line Rtime1=RTime(iMonth...

About spatial discretization

Dear all, I am testing different spatial discretization to save computation time for MC. I have tested different setups of nodes so that I can use the least nodes but still get similar profile of soil moisture. All the setups are listed here, but I know n73 and n61 can be problematic because the gre...
