| Hello everyone, I would be very grateful if anyone could tell me where to find expressions to determine the divergence of a tensor in curvilinear coordinates. I found one in a textbook that confused me and didn't match the result produced by... |
| I've never used this code with text. I think I'd better do some more research. Sinval |
| Hello everyone, Is it possible to use the **DSolveChangeVariables** function to reduce the following PDE? D[f[t, x], t, t] == a^2 D[f[t, x], x, x] + b Exp[c f[t, x]] Regards, Sinval |
| Hello everyone, I installed version 14.2 and the FF function does not work when I import 2D DXF files. It returns a blue square. In version 14.1 this problem also appears. In previous versions it works normally. I used the codes below: p1 =... |
| I thought of this too. Thanks David for your attention. |
| Hey guys, I'm trying to insert the "FluidLoad" option into the FluidFlowPDEComponent component, but nothing happens. Does anyone know how to do this? I'm using version 14. vars = {{u[x, y], v[x, y], p[x, y]}, {x, y}}; pars = ... |
| I am very grateful Eric for this information. |
| I checked this answer and was able to create the button. I am very grateful for your attention Rohit. |
| Hello everybody, I created a grid, with the TabView function, which has two tabs, but they have different sizes and the TabView function always scales the tab by the one with the largest size. Is there any way to make TabView resize each tab by... |
| I didn't know about FunctionDiscontinuities. I liked this procedure. I am very grateful for the information Gianluca. |
