Calculating volume @halirutan The MinRecursion doesn't work either. |

Calculating volume @halirutan When I said: "as it goes from 0 to 540 and does not assume any other value between this range", I meant that, i.e., for any vmax <= 1000 I get a 0 and for any vmax >= 2000 I get a 540. However, when I use RegionPlot3D[], the region is not 0 when vmax = 1000, but continues decreasing when vmax is less than 1000. The same happens for vmax>2000: it does not reach it's maximun value when vmax=2000. I.e., for vmax = 3000, I get the same 540 though the volume has increased. |

Calculating volume @Michael E2, Yes, but didn't work as well. And when the Integrate finds 0, NIntegrate finds the following error (I think this information does not help, but just in case...): NIntegrate::izero: Integral and error estimates are 0 on all integration subregions. Try increasing the value of the MinRecursion option. If value of integral may be 0, specify a finite value for the AccuracyGoal option |

Calculating volume Is it possible to calculate the volume from an already plotted function (i.e. volume of the RegionPlot3D)? If it is, my problem may be solved. |

Calculating volume Hi, Murta and Silvia! The problem is that I don't have the explicit form of radFld[]. When I used the code: Integrate[Boole[(radFld[Grp, "Bx", {x, y, z}] - Btotal)/Btotal <= vmax], {x, -3, 3}, {y, -3, 3}, {z, -10, 10}] I was just using the same method shown on Mathematica website: reference.wolfram.com/mathematica/ref/Boole.html, when they calculate the area of a circle (3rd example of Basic Examples) |
