Hi everybody,

I have a file containing a block that I need to initialize. The geometry is a bit complicated, since it contains a lot of concavities.

The thing i cannot understand however is why when i click on "Solve" Paraview 17.2R2 for Windows 32bit tells me "one or more entities could not be initialized" while Paraview 17.2R2 for Linux 64bit initialize it correctly. The problem is that the Windows PC is more powerful than the Linux one and I would like to use it to create and export my mesh.

What should i try to do?

PS: i realize that i'm not giving you many information, but except for upload the file (that is >100MB) i don't know what else could help addressing the problem. If there is anything you need to know to better understand the problem, i'll provide it as soon as possible.

Thank you,
Luca

My guess is because you're using 32-bit version on Windows and the 64-bit version on Linux. From my experiences the 32-bit version is roughly limited to about 10 million cells. Meaning the 32-bit version of Pointwise can't address enough memory to initialize an unstructured block over about 10 million cells.

The overall geometry is pretty far from 10M cells: I got ~2M cells in two structured blocks and 1M cells in another unstructured block. The block that fails to be initialised is a fourth block that the Unix version fills with 667k cells.

Do you think that the problem could be the memory allocation anyway?

By the way: both the PCs has 8GB RAM.

PS: i forgot to write the error in my previous post. The error message is: "one or more entities could not be initialized"

Did it give more information? E.g. did it report some coordinate locations where the error occured? Often when this happens there is some peculiarity in the surface mesh that prevents the volume mesh from initializing.

More of an FYI as it won't matter in this case because the mesh is relatively small, but even though you computer has 8GB, because you're using a 32-bit version of Pointwise it will only be able to address 4GB.
