I am trying to calculate a quantity from its density in 3D over a rectangular 2D window frame the following way:
mflxx = Integrate[
mi3ret[[1, 1]], {y, -w/2,
w/2}, {z, -(c/2 + zf + d/2), -(c/2 + zf + d/2 + h)}]
where mi3ret[[1,1]]
is a fairly long expression containing only elementary functions of the x,y
and z
variables, and it is the x-component of a 3D vector function. It also contains some constant parameters, like a,b,c
. zf,d,h
are additional constants for the definite integral. After a long calculation the WolframKernel
is killed by the OS without any message or CrashReport. So, after rebooting the machine and running just Mathematica and the Activity Monitor, I made some screenshuts to see, how the memory is used and put the memory related value into lists. See notebook attached, where the 0 minute is really after about one and half hours into the run. The machine is an early 2011 Early MacPro with 64GB memory and a 500GB Flashdrive partitioned into two 250GB partition. So, the questions are: 1. Why the WolframKernel
is killed without a trace? 2. Can the OS tuned in such a way that Integrate
can finish its run? 3 Is there a command or function in Mathematica that would alert to the coming doom and would allow the examination of the status of the machine, including the status of the WolframKernel
? 4. Is it possible to configure Mathematica to use, for disk based intermediate storage, the partition that have more free space, /the boot drive itself has 150GB, the other partition has 230GB free space/ ? Thanks ahead, János
