| I would like some tips to implement, in the NDSolve function, the following expression below with a NeumannValue: Derivative[1, 0][u][5, t] == -h*(u[5, t] - u1) Was it something like this? NeumannValue[Derivative[1, 0][u][x, t] +... |
| This example of PDE I found in a textbook and would like to know is there any way to solve it using DirichletCondition or NeumannValue or some other way. eq = {50*Derivative[2, 0][T][x, t] == 2423750*Derivative[0, 1][T][x, t]}; inc =... |
| Resolve the following PDE: pde = {D[u[x, t], {x, 2}] == D[u[x, t], t]}; inc = {u[-L, t] == u[L, t], Derivative[1, 0][u][-L, t] == Derivative[1, 0][u][L, t], u[x, 0] == Sin[x]}; DSolve[Join[pde, inc], u[x, t], {x, t}, Assumptions -> L... |
| The DiscretizeRegion function works for the cone below. sr = ParametricRegion[{h Cos[x], h Sin[x], h}, {{x, 0, 2 \[Pi]}, {h, 0, 3}}]; DiscretizeRegion[sr] However, does not work for the cylinder below. Does anyone have any tips? sr1 =... |
