MOHID Forum

Hello everyone, My aim is to determine the resisdence time of the water masses in the Guadiana estuary. For that, I am using the lagrangian module and boxes, but with a curvilinear grid. I read somewhere on the forum that is not possible to automaticaly create the boxe file with that kind of grid so...

Hi Mohiders, Is it possible to impose a variable exterior value at the water properties boundary (e.g. using a time series)? in alternative is it possible to change the exterior value from one run to the other when e do a continuation run (it seems that in this case the model keeps the original init...

Hi guys, I am working on a simulation of tsunami in the Strait of Messina. I'm using data from a tsunami which destroyed the city in 1908 . The fault which originated the wave is not include in my bathymetry (being further south) and I was wondering whether I should consider the tydal component as w...

Hi,

just for the record, After a suggestion of Luis the K_CELL value was missing!

Basic Mistake........

Thanks again Luis

Hi again, I now already know the line where it is cracking: it is in ModuleHydrodynamic in subroutine ModifyWaterDischarges in line 34625: Me%WaterFluxes%Discharges(i, j, k) = & Me%WaterFluxes%Discharges(i, j, k) + AuxFlow it seems that it is not constructing the discharge well ????? thanks agai...

Hi, Im trying to use a discharge of the type crest wire, I've already seen that in the keyword's database it is still the old version FLOW_OVER : 1 but I have searched the code and changed my discharges datafile to DISCHARGE_TYPE : 2 the discharge file I've used is: <begindischarge> NAME : Descarreg...

Hi everybody :D I am having problems opening time series with the time series editor: it opens the file and gives me the window to choose the fields, but when i click draw it gives me the error shown below. the time series was created with mohid and have closed ok I'm using gui version 4.9.2732.3226...

Dear Mohiders,

Can anyone help me to find out what are the variables in the .img file (and the respective units)?

X
Y
WIDTH
HEIGHT
MIP_MAPPED
MAINTAIN_RATIO
ALPHA_VALUE

best wishes to all

Hi Luis, Thanks for the help, I think that we will choose to build a small program to read the hydrodynamic's results file produced by the telemac, interpolate to a 3D Cartesian grid in a way that guarantee mass conservation in the Cartesian grid and then write a mohid's binary file of the \"hydrody...

Hi everybody, I have a Brasilian student down here in Algarve that is trying to integrate mohid WQ model into Telemac Hydrodynamic. What she needs is to transform an hydrodynamic file written by Telemac using a triangular mesh into a standard Mohid's hidrodinamic file. Any tool avalable to help her ...

Hi, After a small conversation with Paulo it was clear that it would be very useful in a future revision of the Lagrangian Model that the particles could be linked between the father and the son models. In our case in Algarve the submodels are only a small part of the estuary and if that link doesn´...

Hi, I'm trying to run in version 4.6 a simulation wich works fine in ver. 4.3 It have a lagrangian point discharge with constant flow and concentration (10000) but the particle's concentration are 2.0 everywere. is there any modification? new keyords or something that explains the changes from ver. ...

Hi everybody, :D I'm trying to use water quality in Lagoa dos Patos (Brazil) wich is in the Sothern hemisphere. Do the solar radiation model Mohid_Type works there? I was looking in the code and it looks to me that the solar declination expression: Declination = 23.45 * cos((172.0 - JulDay) * 2.0 * ...

Hi, In module hydrodynamic there is a \"WIND\" keyword. Does it means that the model is going to use the wind fields to compute the wind shear stress? how do we prescribe the CD in that case? In module InterfaceWaterAir there is the \"wind stress X\" and \"wind stress Y\" keywords. if we prescribe v...

Hi, I need to impose the elevation in the open boundary using a time series instead of the usual harmonic component method. Is it possible?
