Error when loading fluid mesh created in Sim. environment

[Andrej_Raskopf]

Hello all,

i successfully used NX10 thermal flow for simulations with less than 30 million elements. My current simulation model has more than 30 million elements. After creation of mesh with Write Solver Input File, i try to load the mesh in post processor to visualize the mesh quality. After some minutes i got this error:

Result not loaded. Unknown error occurred.

Hardware i use:

Workstation Fujisu

Processor Intel Xeon CPU E5-1650v3 3,50Ghz

64GB RAM

graphics card NVIDA Quadro M4000

Do you have any ideas, what can cause this issue?  

Thanks in advance.

With best regards,

Andrej Raskopf

Are there any additional messages in the syslog?

Hello,

thank you for fast replay.

Attached you can find the additional messages in the syslog.

This shows the few lines where the Unknown Error dialog box above was generated. I can tell if you have inadvertently omitted anything preceeding this which may provide a clue.

The best thing to do for this is to start a new session, try to open the results. If you encounter the error, immediately copy the syslog and post the entire text file as an attachment.

That provides more info. The relevant lines are:

*** EXCEPTION: Error code  902 in line 171 of o:\ugnx1003\ip5\src\syss\sm\ind\sm_init.c at Tue Apr 25 14:49:10 2017 Mitteleuropäische Sommerzeit
+++ Bad size (2147483583) for allocation request

Bad size for allocation request is a memory allocation error. The number reported (2147483583) is very near 2GB (2*1024*1024*1024 = 2147483648), so this seems like it may be a code problem where something is still using 32 bit integers.

Please log an issue with GTAC.
