What version of python is anaconda using? See if you can ascertain the anuga version. Ie run import anuga print(anuga.get_version()) Also it would be interesting to see if any of the dll files are in the appropriate directory. Can you check out the directory C:\Users\Bisag\anaconda3\envs\pyqgis_env\lib\site-packages\anuga\abstract_2d_finite_volumes and see if the dll files exist. Your conda install should have provided those! It would be useful to track down the problem. But as mentioned maybe a...

There seems to be a problem with your anuga installation, in particular the location or creation of the file neighbour_table_ext.dll How did you install anuga?

Rup, the example code you have provided doesn't have an if statement in the evolve loop. Can you provide the actual code you are using. Also in the email the python indentation has been lost. I assume the code is correctly indented in the file? I would suggest creating variables stage = domain.quantities['stage'].centroid_values elev = domain.quantities['elevation'].centroid_values before the evolve loop and calculate the depth specifically inside your evolve loop depth = stage[indices] - elev[indicies]...

hello, I have implemented an if condition within my evolve loop to stop the simulation once the water depth in a specific downstream area (covering the river and floodplains) falls below a certain threshold. Although the code runs without errors, the simulation stops as soon as it begins. As a beginner in Python, I am unsure why this is happening or how to ensure the simulation only stops after the water has actually arrived and then receded. ds_polygon = [[619708.796,3085199.395],[620345.056,3090989.363],[665901.284,3079345.802],[654066.845,3061594.143]]...

Hi Rup, Of course you could go into the anuga code to do this, but you can probably do what you want within a standard anuga script. You can run multiple evolve loops of some fixed duration within a while loop. Break out of the while loop when your flood condition has occurred.

Hello All, I am developing a flood simulation model using ANUGA Hydro and I am interested in automatically detecting when the flood event has concluded. My goal is to configure the simulation to terminate as soon as the water depth is zero. (no floods) returns to zero.

I am planning to run a large-scale 2D flood simulation and I need advice on the necessary computational specifications.

Dear Sir, The documentation you shared on the visualization of .sww on QGIS using crayfish has helped. Thank you so much for your prompt response sir. Regarding sww2dem conversion, It is currently falling in to southern hemisphere instead of original northern hemisphere,sir.

Hi, You should be able to use qgis directly on the sww file. Here is some documentation I have just recently added. https://anuga.readthedocs.io/en/latest/visualisation/use_qgis.html Qgis doesn't pick up crc from the sww file so you need to manually set the crc for the sww mesh layer. I will have to look into the problem regarding sww2dem.py. It is strange that the zone and the shifts have not transferred over correctly. Perhaps a problem picking out which hemisphere? There is also a make_geotiff...

Hi there, I have done this at a point (thought I had the equivalent for a line) but I want to do the same idea along a polyline as follows: I want to create a Poly Line along which during a run the Depth of flow is interogated, when the depth reaches a pre-defined value, a flow Outflow is created...(Taking water off the domain) then the procedure continues along the polyline... with a nominal mininum distance down stream... So for example... the next outflow must be Xm (50-60m) along the line....??...

Actually Thinking about this, Mannings equation may help ? Would it be reasonable to imply the slope from the velocity ? So if : V = R^(2/3)S^0.5/n then: S = (Vn/(R^(2/3)))^2 .... This means if I store Mannings n as a Quantity in the SWW file this can be determined ???
-
How wide is the Flume, and what are the wall boundary conditions ? What is Friction set as ?
-
Usually I would Check the size of the smallest triangle & very carefully look at how the Mesh is being generated. Sometimes if refinement polygons have points very close together it will create a very small triangle. The Area of the smallest triangle is used to set the dynamic time step.

Dont know about Parmetis, but ANUGA already can run in Parallel ?
-
Extracting Time Series from the SWW is quite simple with: sww2csv_gauges(file_name, gauge_file, out_name, quantities = [i], verbose=True, use_cache = True) But what about if I want to extract the Slope of the Water Surface (Stage-Slope) as time series ? This can be used for a Bed Shear Approach ?

George Giannakopoulos posted a comment on discussion Help
Many thanks for the detailed explanation and the example code, Steve. You raised exactly the point that puzzled me, i.e. that neither parallel_rectangle nor Parallel_Domain currently fill tri_l2g, node_l2g and the likes. Good to know that, apart from the broken functionality in storing sww files, the evolve loop is otherwise functional. I noticed that you raised an issue on GitHub for this, so I guess it is better to continue the discussion and report on progress there. All the best, George On 7...

Hi George, It probably would be good to get parallel_rectangle working again! parallel_rectangle hasn't been used for a number of years and at present doesn't provide enough info to work perfectly with the anuga current code, in particular creating sww files! We need to extend parallel_rectangle to provide information defining the translation from local to global numbering (via arrays tri_l2g and node_l2g) and information like number of full and ghost triangles. Also the current code assumes that...

OK. But why do you want to parallelism mesh generation? Usually that only accounts for a small fraction of the time spent. Most if the time normally goes into the simulations (which is parallelized).

Jayashri Pawar posted a comment on discussion Help
Hi Stephen , What is difference between 2_0 algorithm and DE1 algorithm . Can we use 2_0 algorithm insted of DE1. Thanks .
-
Hi Jayashri, The timestep constraint is Delta t = min over all triangles. {Diameter of triangle} / {max characteristic speed within triangle} So timestep is controlled by both size of triangles and characteristic speeds within the triangles. So it is very important to ensure that there is not even one unreasonably small triangle produced via the meshing process. Characteristic speed is calculated as max U +sqrt(g h), U is fluid velocity and h is water depth. So the usual back of the envelop calc...
-
Yes , we are taking care of tringle size. But still we are not getting good performance with differential meshing.
-
The speed of the algorithm depends on the number of triangles as well as the size of the triangles. You may have produced some small triangle. You can use the domain statistics to see if there are any unreasonably small triangles, via print domain.statistics() Sometimes boundaries can introduce problems if points on the boundary are too close.

-
Hi Stephen , Thanks for your immediate response, as per your suggestion will stick to the DE1 algorithm . One more issue we are facing is when we use uniform meshing it is performing well but once we add boundaries in a domain and make it differential mesh it takes time trice, While we are not increasing total number of tringles. Any idea for the same ? Thanks.
-
Hi Jayashri, For long time evolutions with tidal forcing I would suggest sticking with the DE1 algorithm, though as you have observed it take essentially twice as much time to solve compared to running with the DE0. Essentially DE0 runs with a first order Euler time stepping and DE1 uses the average of two Euler steps, hence the doubling in computational time, all things else being the same. With flows over very flat terrain I would also suggest investigating using domain.set_low_froude(1) This tends...
-
Currently we are using ANUGA for flood simulation as well as our case includes tidal flows over many tidal cycles . Current algorithm we are using is DE1which is more accurate but at the same time we are looking for the faster one. With DE0 we are facing issues with tidal flow simulation. Kindly suggest the better algorithm . Selection of algorithm will play major role in our case because of large input. Thank you in advance , any help will be apriciated.
