Hi users,
Is there limitation in pizza for reading multiple dump files? I have 23351 dump files but can not read all for converting into vtk. After reading several files it stops working.
Best,
Ram

Hello Ram,

I would suggest you give our tool lpp a try - it can be found in the download section. pizza loads all the dump files into memory prior to writing them to vtk, and so if you have many dump files, you will run out of memory during processing. lpp acts as a front-end to pizza and processes only some files at a time, which will keep the memory demand reasonable. It also works in parallel, so if you have a multi-core machine it will most likely speed up post processing.

greetings
Philippe

Is the dump file somehow limited? I do a simulation and dump the stl files and the particles

dump dmmp all custom 2000 post/dump.fill id type type x y z ix iy iz vx vy vz fx fy fz omegax omegay omegaz radius v_stressonparticle
dump dumpstress all mesh/gran/VTK 2000 post/wall*.vtk stress stresscomponents

but i get 681 dumpsteps for the particles and over 2000 for the stl output. At some point the particle dump stops writing states out.

thanks in advance
Joshua
