Re: How to generate contact netcdf?

I have created a child grid using the method that I had been using, which works fine for old version ROMS and COAWST. But the new model needs contact.nc. So initially, I tried this name = 'contact.nc'; c_contact(name,true,2) grd = {'parent_grd.nc','child_grd.nc'}; [S,G]=contact(grd,name); My error m...

How to generate contact netcdf?

Hi, I have a model grid from years ago. And I need to generate a child grid and the corresponding contact netcdf file. The problem is the old model grid that I have is not created from the rutgers/grid tools. So when I use coarse2fine.m, it is not working. Can someone show me how to deal with this? ...

Re: Abnormal temperature along the boundary

I am running a pure tidal simulation. So the only input forcing that I am giving is the tide.nc in different tidal components. Everything else is using a default analytical solution from ROMS. In this case, where should I go to fix the temperature? Do you think it is the temperature that causes abno...

Hi, I am running a tidal simulation with river discharge. On the day 30th, the model starts to show abnormal current speed, negative temperature along the east boundary.

Re: Model blow-up after adding river discharge

Hello Kate,

Thanks for the quick response. :) I really appreciate it.

Do you suggest I should change to

Code: Select all

LtracerSrc = T T
or

Code: Select all

LtracerSrc = T T T T
For the Qshape, I am simply using the example from riverplume1 in the ana_psource. What do you mean that it may not be stable?
