| Hi All, I'm trying to formulate and solve a pde which models thermal radiation between two bodies using a Neumann boundary condition. I've created a mesh and want to capture the thermal radiation heat transfer between element 106 and element 19... |
| Hello All, I have the following equation which I'd like to solve for Mt using FindRoot: calcMt = {((At P) Sqrt[\[Gamma]/RSpec] Mt)/(Sqrt[ T] (1 + (\[Gamma] - 1)/2 Mt^2)^((\[Gamma] + 1)/( 2 (\[Gamma] - 1)))) -... |
| Hi Mike, Apologies for the delayed response but many thanks for the great tips. I hadn't come across the programmatic notebook nor the in-built verification tests before. Many thanks, Archie |
| Many thanks Marco, much appreciated. Interestingly, if you use solve with the expression equated to zero it also works (in my original post I'd tried Solve without equating the expression to zero). Clear[del] del[x_] := Module[{y, dP,... |
