core dump - engrid or machine limitation
 

Dear Bruno, dear Oliver,

for a mesh resolution study I would like to generate a mesh as fine as possible. At the moment I struggle to generate a boundary layer, where the surface mesh contains more than 2M surface cells (engrid 1.4). (Error: 3698 Speicherzugriffsfehler (Speicherabzug geschrieben))
In the old forum I read that only volume meshes of ~8M cells were generated in engrid so far (in 2010), so I ask myself if the limitation in engrid is reached or if my machine limits me in generating finer Meshes (32 GB RAM, no swap) As far as I see, the memory is not consumed at time of abortion...
What Meshsize is known to be generated successfully?

best regards

Georg

Hi Georg,

Are you positive that the engrid binary was built as a 64bit application?
You can confirm this by running:
from within the folder where the binary is located (possibly "engrid/src"). If you can run it from any folder, then you can use this command:
Among the first things it should tell you should be this:

Dear Bruno,

yes, I can confirm that engrid was built as 64bit application. Got the output
best regards, Georg

Hi Georg,

I'm on vacation these coming days, so I could use more specific information on the kind of test case I should be trying to do (number of surface mesh faces, volume mesh characteristics and so on). If you could share such a case would be great.

Because if my guess is correct, there is a limitation in the number of faces count to 2 million or 4 million, but I need a test case to isolate this.

Best regards,
Bruno
