Turbulent diffusion

Paulo,
I would like to know how in the mohid the diffusion coeffcient of each water property is defined in the water properties module.

Dear Francisco, it is not possible to define directly a value variable in time in the border. The only way is to active the assimilation module. The assimilation module allow the user to relax any property (flow or water) in any cell using the follow formula dP/dt = (P(assimilation) - P) / Decay Tim...

Impose water properties using a time serie at open boundary

Dear Paulo, I would like to do is like, similar to the water discharges, to input a monthly value for some of the water properties, that could be read from a file. As an example one of my water properties would look like this: <beginproperty> NAME : temperature UNITS : ºC DESCRIPTION : temperature I...

Hi, Nuno I check the source code and the Time Serie Option is active. The ModuleInterfaceWaterAir creates time series with extensions \".sri\". In the block property you want to do a output with the time serie format you need to define the follow keyword. <beginproperty> TIME_SERIE : 1 <endproperty>...

Dear Rui, I have already implemented this new option but this only be available in the next version update. To define directly the density filed you only need to put in the water properties a Keyword block similiar to the one below. <begindensity> NAME : density UNITS : kg/m3 DESCRIPTION : density p...

Digital Terrain Tool

The new version of MohidGis some how assumes that the output files of Digital Terrain Tool are input files. The consequence of this is that the MohidGis gives an error of the type \"The file X (output) do not exist\".

Wind Velocity Definition

Dear Nuno, you have two ways of defining the wind velocity. Option 1 - You can define the wind velocity using as input the wind velocity components X (m/s, west-east) and Y (m/s, south-north); Option 2 - You can define the wind velocity using as input intensity (m/s) and direction (degrees, meteorol...

In the data file (see keyword IN_TIDES in the nomfich.dat file) where you defined the tidal guages you can defined the water level associated with a tidal guage in several ways. For example in case of the amplitude evolution (keyword EVOLUTION) you have three options: EVOLUTION : Constant EVOLUTION ...
