What is the advantage of Boundary Element Method over Finite Element Method ?

less elements, so less complicated maths.  \n\nYou get a less accurate result, which I don't consider an advantage.

Try using a non dimensional correlation for the Bio number or possible Prandtl number. I can't remember off the top of my head, but one of them should relate your Mach number to pressure or viscosity allowing you to have only one unknown. Another idea would be to model the situation with a known boundary layer pattern and find where the boundary layers meet. Check the solution and see if it is reasonable.

For a give weight of material, a flat material is stronger if you will consider a wide flanged beam to be a series of flat materials. \n\nIt really depends on the application. For beams, circular cross sections are not as efficient as the H shape of a wide flanged beam.\n\nFor columns a circular cross section can be more efficient depending on where the load is applied.\n\nThat is the reason structural engineers are employed to design structures. They can chose the correct configuration for each piece.

Advantages:\n* Share hardware such as printers e.g. 12 computers in a room, instead of 12 printers for each computer, just one is needed\n* Share software and opearting system (Multi-user licence)\n\nDifferent methods of networks are:\nRing:\nA local-area network (LAN) whose topology is a ring. That is, all of the nodes are connected in a closed loop. Messages travel around the ring, with each node reading those messages addressed to it. One of the advantages of ring networks is that they can span larger distances than other types of networks, such as bus networks, because each node regenerates messages as they pass through it. \n\n\nStar:\nA local-area network (LAN) that uses a star topology in which all nodes are connected to a central computer. The main advantages of a star network is that one malfunctioning node doesn't affect the rest of the network, and it's easy to add and remove nodes. The main disadvantage of star networks is that they require more cabling than other topologies, such as a bus or ring networks. In addition, if the central computer fails, the entire network becomes unusable. \n\n\nBus:\nA network in which all nodes are connected to a single wire (the bus) that has two endpoints. Ethernet 10Base-2 and 10Base-5 networks, for example, are bus networks. Other common network types include star networks and ring networks. ]\n\n\nMesh:\nAlso called mesh topology or a mesh network, mesh is a network topology in which devices are connected with many redundant interconnections between network nodes. In a true mesh topology every node has a connection to every other node in the network. \n\nThere are two types of mesh topologies: full mesh and partial mesh. \n\nFull mesh topology occurs when every node has a circuit connecting it to every other node in a network. Full mesh is very expensive to implement but yields the greatest amount of redundancy, so in the event that one of those nodes fails, network traffic can be directed to any of the other nodes. Full mesh is usually reserved for backbone networks. \n\nPartial mesh topology is less expensive to implement and yields less redundancy than full mesh topology. With partial mesh, some nodes are organized in a full mesh scheme but others are only connected to one or two in the network. Partial mesh topology is commonly found in peripheral networks connected to a full meshed backbone. \n\nDiagrams from http://www.webopedia.com/quick_ref/topologies.asp

A thin flat cell will diffuse faster than a cube shaped cell.\n\nIt all depends on it's surface area to volume ratio. The higher the ratio is, the higher the rate of diffusion.

Same as my previous answer except that a cantilever deals with negative moment although it makes no difference.  For hollow sections with the same Area as a I or solid rectangle would have much higher inertia because all of their mass is as far as possible from the centroid making for a very high EI and a very low deflection

Finite Element Analysis (FEA) is a process in which you solve equations.  These equations can relate to stress, as mentioned above, but also heat, diffusion, chemical reaction, or anything you want.\n\nFEA is a system of solving these equations in which a large object is broken into many elements.  Then equations are solved for each element and stitched together to give the final answer.  The method is now pretty standard and optimized to give fast reliable results in many cases.

minimal. \npower to weight ratio is significantly more important, as is wing design (the "lift" it can generate).\nplacement only concerns the weight distribution.

CONFORMAL MAPPING\nIn a limited group of problems one can use a short cut to the solution of the\nLaplace's equation, conformal mapping. The problem has to be 2D (two\ndimensional), i.e., the boundaries, boundary conditions and sources contain\nonly two variables, x and y say.\nSome examples where this method can be used is: the electrostatic potential;\nheat conduction; flow of fluids.\n\nThe conformal mapping relies on the properties of analytic functions. \n\nAny function that has continuous partial derivatives of the second order and\nthat satisfies the Laplace's equation is called a Harmonic function.\nThus both the real part, u, and imaginary part, v, of f are harmonic\nfunctions.\nIf the function f = u+iv is analytic, u and v are conjugate harmonic\nfunctions. Given one of two harmonic functions, the Cauchy-Riemann\nequations can be used to find the other.\nThat u and v are harmonic functions can be used to find the potential. Both\nu and v are candidates for the potential since they satisfy Laplace's\nequation. Alternatively the function f can be viewed as a change of\nvariables, a transformation from the complex z-plane to the complex w-\nplane.\nTransformation of boundary conditions.\nTwo types of boundary conditions remain unchanged by the transformation\nand problems with these boundary conditions are best suited for conformal\nmapping. The types are:\n1) The value of a harmonic function is constant on the boundary.\n(one type of Dirichlet problem)\n2) The normal derivative of a harmonic function is zero on the boundary.\n(one type of Neumann problem)\n(The conditions are that f and its inverse are analytical)\nThe capacitance between two conductors\nIf Q is the electrical charge on either conductor and D V is the\ndifference in potential between one conductor and the other, then the\ncapacitance C is defined to be c=q/v

Nickel is harder than copper and provides better penetration into the target. Copper is softer and tends to mushroom much faster once it enters its target. \nIf you want penetration go for the nickel\nIf you want displacement go for the copper

You have confused 2 different techniques I suspect. \n\nMagnetotelluric methods use EM fields to probe the interior of the earth. Seismic methods use mechanical waves, a different technique.

Both have their advantages...........and disadvantages.

In  a given material of a given cross-section, the resistance increases with length.  Now conduction is the opposite of resistance, so the shorter it is, the better it will conduct.  \n\nEs mayor en una corta.

hi, \n\ni don't know what it has to do with finite element analysis, but the rotation matrix form depends on whether you are working in 2 or 3 (or more) dimensions, and about what axis you are rotating.\n\nthere are examples of a 2-d rotation matrix and all 3 3-d rotation matrices on this page:\n\nhttp://mathworld.wolfram.com/RotationMatrix.html\n\nbasically, the way they work is you take a vector in cartesian coordinates, and operate on it with (in other words, multiply by) this matrix.  the vector that comes out has been rotated by whatever angle you put in.\n\ncheers !

Use Finite Element Method to model the chassis. You can use any software on FEM. To get complete information about chassis (its functions and types of loads and modes of failure, etc.) read any good book on automobile engg.
