Nesting Numerrical Instabilities

Hi, I'm performing a nesting simulation into for a meso-scale model to the southeast brazilian's continental shelf. For tide, I'm using the FES2004 solution and for velocities, salinity and temperature I'm using the Hycom-ncoda's database. Right now I'm trying to nest another domain in the last two ...

Re: Water properties instability

Hi Melissa, let me know about the configurations of your model... What your grid step and how many cells you're setting the discharges? More, what's your application (I mean, what you planning to do?). If you don't have a time serie of temperature and salinity at your river mouth, so you must to enl...

Re: Water properties instability

Hi Melissa, I think this occours cause the model isn't reached the equilibrium. When you set boundary condtion exterior the value defined in the keyword default_boundary is imposed at your open boundary. Tell me what temperatures and salinities of your discharges and what value you're setting for th...

Re: Water properties instability

Hi Melissa, when you don't set the BOUNDARY_INITIALIZATION keyword this is set by the default (INTERIOR), and this means that your values set by default values to the salinity and temperature are set into the open boundary. In your runs you said for low discharges it runs fine, but you've took a loo...

Re: Water properties instability

Hi Melissa, I'm affraid the coefficients that you are changing is not the cause of your error. Taking a look into your study case I realized that you want to simulate a discharge of a river 'till the ocean (and how huge your river, 300 km!!!!!!), but taking a closer look at your keywords you're defi...

Re: Water properties instability

Hi Melissa,

can you post your WaterProperties' keywords here for both simulations? Maybe your boundary conditions (for temperature and salinity) wasn't set properly...

You made so many questions, I'll try to answer the others after...

Re: ERR05 modulus HDF5 Line 3 - FillMatrix

Hi Isabel, let me know if I understood your problem... You want to force your model with wind time serie, right? But are you saving your data in a .hdf5 file? If you want to provide, a time serie to MOHID you should create a time serie with your data, in the same way as MOHID do and so you need to s...

Re: Program Exception - access violation

Hi, I noted that you have a lot of key-words in your hydrodynamic input file. But Ok, let me tell my point: - in the bi_harmonic I think you are using a big value, here is the link that teach how to set the proper value of the biharmonic coef. http://www.mohid.com/wiki/index.php?title=Biharmonic - g...

Re: How to make HDF5 files with Matlab

OK, but I think the best way is to re-run your matlab code in a matlab 2008. I never tried to install the newest hdf5 library or compile the MOHID to generate a new executable, but I think it is a quite difficult to do, and you will need the Intel Visual Fortran 2008 to compile the MOHID. Best regar...

Re: How to make HDF5 files with Matlab

Hi Robert, this occurs 'cause the hdf5 library version used on your matlab to write the hdf files. The MOHID accept only the version (I'm not sure) 1.6.8 or lower. The version 1.6.8 is used on matlab 2008 or lower. Then, the solutions are: -Run your matlab script in a matlab 2008 or lower, or -Downl...

Restart a crashed run

Hi, I'm trying to restart a crashd run and I followed the steps as written in the Mohid official site. But I have two doubts: -first: when I generate a new run at the same time of the last fin's file saved, I need to change the initial date of the father model too? -and, when the I run the new run, ...
