Dear Carla, this is a example for defining an instant emission of choesive tracers in a box: OUTPUT_TIME : 0. 3600. OUTPUT_MAX_TRACER : 1 OUTPUT_CONC : 1 DT_PARTIC : 10.

Mohid Gis do not allow chaging cells with values equal to the fill value (this value can be defined in the properties of the GridData). The way to avoid this problem is, for example, your fill value is -999 change to -1000 in the Grid Data/properties (F4) and then you can change the fill values usin...

When I have the bottom legend ON there is a problem between the mouse and the coordinates. For example, if a create a group of points xyz with the bottom legend OFF the points appear where I click. However if I do the same procedure but with the bottom legend ON the points appear with a vertical tra...

Hi Luis,
the Mip Mapped option was enough to solve the problem.
What this optiion do?

Dear Mohiders, I have a problem with the background images. When I try to use as background image a portuguese topography chart in jpg or gif I only see a white square. A collegue of my (Pedro Ferreira) solve the problem cutting part of the figure. Do you now what is the problem ? Do you now a way t...

A new non hydrostatic version of Mohid version is underdevelopment. The model is now being test for 3D cases (internal tides). However, the animation below show results for a 2D domain. This animation show the Kelvin-Helmholtz instabilities in a lock exchange test. http://www.mohid.com/StudyCases/lo...

Olá Francisco, I send the link to three files one is a manual where all the equations and the new resources of MohidJet are described MOHIDJET.pdf. Another file is outfall.dat is an example of what can be one way of defining one group of ports (ModuleJet data file - near field). The other is Lagrang...

I Mohiders (Paulo), Did you remember that I commented you during my stay in Lisbon about a project that involved the discharge of very saline water through an outfall?. Actually I´m working in that project and I would like to know if you could provide me of some help in deffining the parameters. My ...

The help is not working. I go to help/contents nothing happens. I went to the Mohid directory and the Help file (c:/program files/mohid/MohidHelp.chm) is there and is working. Can any one solve this problem (any one = Frank) :P . This problem happens in this new version and in the last one. Paulo

Just another comment. If you want to see arrows (ex: velocities) you need to define the size arrows and ALSO THE ARROWS COLOR.

The visualization in Mohid Gis is still little tricky. In a next version the user will have a more friendly Mohid Gis.

Hello Andrea, the MOHID handles wet/dry cells. You can see the description of our algorithm in a paper published in the Oceanological Acta. See a version of the paper in this site http://maretec.mohid.com/PublicData/Products/Papers/5.pdf See the chapter where boundaries are describe (Land Moving Bou...

Dear Mohiders,
I have problems with the buttons of the Post-Processor. Basically the buttons appear in the wrong place and when I try active them nothing happens.
How can I solve this problem?

Dear Nuno, the diffusion coefficient for each water property in the horizontal (Kh) is computed in the follow way: Kh = Vh * Schmidt_NumberH in the vertical (Kv): Kv = Vv * Schmidt_NumberV + Molecular Diffusion Vh - horizontal turbulent viscosity Vv - vertical turbulent viscosity Vh and Vv are defin...
