How to Make a Hexagonal Grid? 1

All answers are great. Few more options are available.When I am dealing with these kinds of problems, I like to rely on simple math and copy shapes with numerical values, rather than moving them with mouse. If you know the height and width, do some calculations how low and on the side you need to move polygons and copy with pressing enter etc. - in a pop up window set numbers to move the shape, press copy and repeat action with Ctrl/CommandD as much as you like. Illustrator can be used with numbers in many situations

grid.org

grid.org was a website and online community established in 2001 for cluster computing and grid computing software users. For six years it operated several different volunteer computing projects that allowed members to donate their spare computer cycles to worthwhile causes. In 2007, it became a community for open source cluster and grid computing software. After around 2010 it redirected to other sites

Positioning game object on a grid

Yes. But it depends on your goal, whether it's the best solution or not. I would do it like that: -Create a large array for tiles (grid layout) -Put on each array the specific texture (grass, sand etc..) -And put items on the specific tiles. Huge textures can cause problems on some of the devices like old android phones. E.g they do not support textures larger than 1024px.. So I would use arrays and put each world tile on it. (Sorry for bad english)

Power Grid crisis in AMerica?

LOL While it would be nice to find a more efficient ways to obtain electricity, we wont run out of it. Thats like saying water will cease to exist. It wont happen

Number of paths from a grid corner to visit all other points on a grid

Partial answers for the $n times 2$ grid:Without diagonal moves allowed, note that there's exactly one path ending in each row, so there are $n$ paths.With diagonal moves allowed, classify paths as follows:This yields the recurrence $x_n2=2^n12x_n14x_n$, so we have$$ beginpmatrix x_n1 x_n2 2^n1 endpmatrix = beginpmatrix 0&1&04&2&20&0&2 endpmatrix beginpmatrix x_n x_n1 2^n endpmatrix $$so $x_n$ is the first element of $ beginpmatrix 0&1&04&2&20&0&2 endpmatrix^n-1 beginpmatrix 162 endpmatrix $.You can efficiently exponentiate this matrix to compute values of $x_n$, or diagonalize it to obtain a closed-form solution.

What is basic different of stand alone system from grid connected system in PV system?

The PV Grid-Connected Systems Grid connected PV system is applicable for residential. As the name, grid connected system is power generation by solar photovoltaic system that connected to the grid or utility. In a grid-connected (some times called grid-tied systems), solar energy commonly used by owner during day time. At night on the other hand the owners receive power from electricity grid. The main advantages of grid connected system are (1) No need to précised to fulfill peak loads, those overages could be taken from the grid. (2) The possibility of exporting energy (means earn some money) when surplus energy generated (2) Grid connected however should not emit the noise which can interfere with the existing grid. Moreover, the must be an appropriate inverters to control power when grid is down. Grid-connected systems must meet utility requirements. For example, inverters must not emit noise that can interfere with equipment reception. Inverters must also switch off in cases of grid failure. Finally, they must retain acceptable levels of harmonic distortion, such as voltage quality and current output waveforms.

Multigrid on "not Perfectly Rectangular Grid
Multigrid on "not perfectly rectangular” gridLets say that you have the following grid composed of rectangular elements:Now if you perform your interpolation assuming a normal structured rectangular grid then you will be introducing errors associated with this inaccurate interpolation. In other words when you restrict your residual vector and when you prolong your error vector there will be errors from the interpolation. Now if your grid is "close" to being a normal structured cartesian grid then this may work, at least at first, but I suspect one of two things will happen depending on how far off you grid is from being rectangular:1) You might find that the multigrid begins to converge at first. After all initially your error is large anyways and your "approximate" interpolation really just means that some nodes are slightly over represented while some are slightly under respresented. However you may find that the convergence stagnates as the solution becomes more accurate and the interpolation errors become more important.2)Another possibility is that the multigrid does end up converging, but not as fast as it should if you had used the correct interpolation.Basically by being off with your interpolation you are weighting the importance of certain nodes inaccurately. For example in 2D if you are weighting a given node as:beginbmatrix 0.25 & 0.5 & 0.25 0.5 & 1.0 & 0.5 0.25 & 0.5 & 0.25 endbmatrix when in truth because your grid is not exactly cartesian it should be:beginbmatrix 0.25 & 0.55 & 0.25 0.55 & 1.0 & 0.49 0.28 & 0.52 & 0.30 endbmatrixthen this will result in some error. Whether this error prevents convegence will likely depend on how far off your grid is from being cartesian. While AMG is more difficult to understand/implement it sounds like it is the correct method for your grid. Applying geometric multigrid to an "approximate" rectangular grid may work, but I would guess that it is a band-aid solution at best. Hope this helps. Update: I think there may have been some confusion in my answer. I am not saying that geometric multigrid will only work with cartesian meshes, but rather that defining interpolation (and hence restriction) on cartesian meshes is easy whereas on non-structured meshes this may be difficult. For example consider the case of even a simple 2D domain with a triangular mesh. Refining this mesh is easy - at least conceptually - but how would you define an interpolation operator between the coarse and fine mesh? I prefer AMG simply because it performs more like a "black box" solver, i.e. doesnt need information on the underying mesh, however this is just my person bias/quirk. Geometric multigrid can work as long as you can provide accurate interpolation operators.— — — — — —If you live off the grid, is there some way you can have your own internet and not rely on other ISPs?If you live off the grid, is there some way you can have your own internet and not rely on other ISPs?If you are rolling in money and technical skill, you could arrange your own link to the internet backbone.Or you can wait till Elon Musk's Starlink starts operating. Even though that will still mean going through an ISP, it will be an ISP that is trying to outcompete all the other ISPs.— — — — — —Connected subsets in a gridThere is a unique solution, and it can be found by logic alone (i.e., human-level logic that does not require backtracking of more than a few steps). A few things to note that help with the process of elimination:By fact 1., the subset $1$ needs to go in one of the four boxes not on any dotted line. Three of those boxes are part of solid-solid-dotted triangles: the subset $1$ can not go at the solid-solid vertex of any of those, either, because its neighbors would have to be of the form $1,a$ and $1,b$, with $a=b$ (because of the dotted line) and $aeq b$ (because they are different boxes): a contradiction. That leaves the upper right-hand corner as the unique location for $1$.By fact 4., $2$ and $1,2$ either (a) both go in the pair of boxes on the lower left, or (b) neither touches a dotted line. If it's (b), then there are three places left that they can go: the two boxes on the lower right, and the box next to $1$ in the upper right. They can not both go in the two boxes on the lower right (even-solid-distance), so one must go next to $1$... that would have to be $1,2$ because of the solid connection to $1$. But $1,2$'s other solid-line neighbors would have to be $1,3$ and $1,4$, which do not have the same highest element, and so (b) is a contradiction. Therefore one of $2$ and $1,2$ goes on the extreme lower left: that's an even-solid-distance from the upper right, which contains $1$, so $2$ must be on the lower left. And $1,2$ is just above it.All the remaining boxes and dotted lines are in solid-solid-dotted triangles (some are in more than one). If $1,3$ or $2,3$ are on a dotted line, they must be connected to the other by it (only two even-size subsets with the highest value $3$), and the remaining vertex in the solid-solid-dotted triangle must be $1,2,3$ or $3$. They also can not go in the boxes on the lower right (even-solid-distance from the upper right), leaving only one box not on a dotted line, so they must be on a dotted line. It can not be the long dotted line (no other highest-number-$3$ and even-size partner), or either of the two short dotted lines an even-solid-distance from the upper right. That leaves the upper left corner and the box to its southeast for $1,3$ and $2,3$, and forces $1,2,3$ into the box above $1,2$ (since the other choice, $3$, can not be joined by a solid line to $1,2$). Now $3$ must be to its southeast, since it's the only highest-number-$3$ partner left.The upper left can not be $2,3$, because the only ways to get from $1$ to $2,3$ with three solid lines use $1,2$ or $1,3$, which are not available; so it must be $1,3$, and the other boxes in the top row must then be $1,4,3$ and $1,4$ (left to right).The rest can now be filled in rapidly. $2,4$ to the right of $2$. $3,4$ to the right of $3$. $1,2,3,4$ to the northeast of $3,4$ (only even-sized subset left). $2,3,4$ connecting $3,4$ to $1,2,3,4$ by solid lines. $4$ connecting $2,4$ and $3,4$ by solid lines. And $1,2,4$ connecting $1,4$ and $1,2,3,4$ by solid lines. And done.
