Re: [Paraview] RungeKutta4 implementation issue
I suggest you attach a debugger to the code and step through. Then
you'll be able to answer your question.
Since the velocity field of your data may be high, it is entirely
possible that the computed next position is outside of the bounds.
Perhaps reducing the step size will help. Try even Rk4.5 with adaptive
steps, this may help if the velocity gradient at the edge of the domain
is very large..
JB
How is it possible???
double *bds = reader-GetOutput()-GetBounds();
printf("%lf %lf %lf %lf\n", bds[0], bds[1], bds[2], bds[3]);
- 0.00 69.00 0.00 69.00
printf("point1[0]=%f point1[1]=%f point1[2]=%f\n", point1[0],
point1[1], point1[2]);
- point1[0]=58.196274 point1[1]=68.862898 point1[2]=0.00
if (integrator-ComputeNextStep(point1, point2, 0, delT.Interval,
stepTaken, minStep, maxStep, this-MaximumError, error) != 0)
break;
printf("point2[0]=%f point2[1]=%f point2[2]=%f\n", point2[0],
point2[1], point2[2]);
- point2[0]=59.002164 point2[1]=69.454414 point2[2]=0.00

Re: [Paraview] RungeKutta4 implementation issue
Hi Fred: As JB suggested, please try using RK45, which employs an adaptive step size that is insensitive to the velocity magnitude and hence is capable of capturing accurate shape of the curve (flow line). Using RK4 (still adopting a fixed step size) does not guarantee a sufficient / desired acurracy of numerical integration (though certainly it is better than RK2) since it is stil sensitive to the velocity magnitude. Recently we improved the flow line integration accuracy issue. For any problems, please feel free to let us know. Thanks. -Zhanping -- Zhanping Liu, PhD Kitware, Inc. 28 Corporate Drive Clifton Park, NY 12065-8662 Phone: 518-371-3971 x 138 http://www.zhanpingliu.org On Mon, Aug 17, 2009 at 5:06 AM, John Biddiscombe biddi...@cscs.ch wrote: I suggest you attach a debugger to the code and step through.

[Paraview] make error when building ParaView 3.6
Hi, I'm trying to build ParaView 3.6 on an Ubuntu machine (w/ Qt 4.5) but I'm hitting an error when I run 'make'. I'm doing the 'ccmake path_to_source' and keeping the default configuration except setting number of processors to 8 (I have a Core i7) and turning on the PARAVIEW_ENABLE_PYTHON and PARAVIEW_USE_MPI. I try to turn off BUILD_SHARED_LIBS, but it keeps switching itself back on (why??). Anyway, it configures fine with just a complaint about Qt PHONON library not found, which I understand is just a warning, not a show-stopper (right?). But when I run 'make', it gets to about 4% and then dies as follows: Scanning dependencies of target MapReduceMPI [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/mapreduce.cpp.o [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/keyvalue.cpp.o [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/keymultivalue.cpp.o [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/irregular.cpp.o [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/hash.cpp.o [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/memory.cpp.o [ 4%] Building CXX object VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/error.cpp.o Linking CXX shared library ../../../../bin/libMapReduceMPI.so /usr/bin/ld: /usr/local/lib/libmpich.a(allreduce.o): relocation R_X86_64_32S against `MPIR_ThreadSingle' can not be used when making a shared object; recompile with -fPIC /usr/local/lib/libmpich.a: could not read symbols: Bad value collect2: ld returned 1 exit status make[2]: *** [bin/libMapReduceMPI.so.pv3.7] Error 1 make[1]: *** [VTK/Utilities/mrmpi/src/CMakeFiles/MapReduceMPI.dir/all] Error 2 make: *** [all] Error 2 So, anyone got any ideas?

Re: [Paraview] make error when building ParaView 3.6

Re: [Paraview] How to set up X connection
When you say do have a login screen in each of the machine, what do you mean? Is it a graphical one or a black window with a login prompt at the top? If you have a graphical login screen, that means you are running X (through xdm or some other display manager). If not, you need to enable X on those machines. This may require installing it - or not if it is already there - and turning it on. How to do that depends on the Linux distribution. Once that's done, you should create a user and make Linux login to that user automatically at boot time. You will also have to make sure that the display is accessible. This may require using something like the xhost command. I recommend searching on the web for more information on setting up X. -berk On Wed, Aug 12, 2009 at 4:06 AM, chew pinglcp8...@msn.com wrote: Dear Berk well, basically we don't have a very clear idea of how paraview deals with parallel rendering. we could ssh -X to any of these machines and run xclock and the X windows does appear at the machine we are from. on the other hand, while trying to start a parallel pvserver, everything works fine until when a client (paraview) connects to the parallel pvserver, and we get a window alerting us about parallel rendering disabled.. by following the thread in paraview mailing list, we got to know that to enable parallel rendering, each of the machine running the parallel pvserver should be able to generate a window to do the rendering work. now in order to do that, we are suppose to have xdm ran on startup. that's where our question is, (because we are not very good at linux) how do we startup the xdm? we do have a login screen in each of the machine. tried setting the usr/bin/env DISPLAY=localhost:0 while starting the parallel pvserver, but still the window alert of parallel rendering disabled persist.
