Definitely you have a problem with your gridata file. Send it to me, I'll take a look. Cheers.

Thanks a lot Luis, you're a master. After making the correction, when I tried to run the simulation another error apppeared: 'CoupleLightExtinction - ModuleWaterProperties - ERR07' What I did was to add the 'cohesive sediment' property to the waterproperties data file, and then it worked pretty well...

Dear All, I am right now testing the first-order decay model for the water properties module and it is giving me some trouble. I have launched simulations with constant T90 and everyting is ok. But when I put a variable T90 (method 1 or 2), MOHID gives the error message: \"OutPutHDF_AditionalFields ...

Hello guys, Is it possible to rotate the viewport in MOHIS GIS? You see, Barcelona coast is not as parallel to the meridian axes as the portuguese coast, it has a skew angle of about 44.4º, so the results look better when rotated. Another thing: the forum \"search\" is not working. You should take a...

I also had problems with MOHIDPostProcessor. When I drag the \"openpoints3d\" datatset to the mapping list, the following error appears: \"Mapping can only be waterpoints or openpoints\". This makes impossible to use the program. This does not happen in MOHIDGIS (here everything seems fine). Cheers ...

Dear Frank,

Can you tell how first order decay in WaterProperties works? I am very interested in it.
Thanks in advance. See you.

Hi Frank, Opening the HDF file with the new MOHID GIS (v. 4.6) looks fine. But MohidWater & Mohid PostProcessor cannot read it. So I guess I'll have to wait till next release... The Large & Pond formulation is for calculating drag coefficient, which does not tell me what is your reference ve...

Dear All, I hope you're all doing well. I am trying to sell--not in the literal sense-- MOHID to the other side of peninsula. We are treating the problem of CSOs in Barcelona, and nearshore simulations are quite interesting for us. As soon as I have interesting results, I'll show them to you. For th...

Dear All, Is it possible to impose a variable decay time (T90) for the 'fecal coliform' property with Eulerian transport model? I have seen that this option is available in the Lagrangian module (T90_VAR_METHOD keyword, I guess), but it seems that the same does not exist for the WaterProperty module...

Cheers All, Let's put this in simple words: I want to simulate shit spills to the sea. Knowing that : i) I do not have too much field data ii) I am mostly interested in bacterial concentracions (fecal coliforms) iii) I want 3D results what is the best (= straigth, short & possible) way to do thi...

Regarding this point, I have one more question: if parent domain is 2D and child is 3D, how is the data for a water property interpolated at the boundary?

You're having stability problems. The square root error means that the program is calculating the square root of a negative value. In other words, the model made a big boom somewhere and yielded a negative value for a quantity that should be positive (water depth for instance). Conclusion: your doma...
