decompose your domain into subdomains (splits)

There is no mesh. It is only the volume decomposition.
I advice you to do it yourself, but I give you the journal file... ********* volume create width 2 depth 1 height 1 brick face cmove "face.3" multiple 1 offset 1 0 0 face cmove "face.1" multiple 1 offset 0 0 0.5 face cmove "face.2" multiple 1 offset 0 0.5 0 volume split "volume.1" faces "face.9" connected volume split "volume.1" faces "face.8" connected keeptool volume split "volume.2" faces "face.8" connected volume split "volume.3" faces "face.7" connected keeptool volume split "volume.1" faces "face.7" connected keeptool volume split "volume.2" faces "face.7" connected keeptool volume split "volume.4" faces "face.7" connected

Also, are you 32 bit or 64 bit...
You are not going to get 32 million cells out of 32 bit Gambit... (the 32 million was just a coincidence... nothing to do with 32 bit... I don't think you could get 15 million cells out of 32 bit gambit...)

I managed to get a 10 million cells mesh on 32 bit version.
No problem untill I wanted to export the mesh. That's the problem.. I had to switch on linux64 bit partition with 8GB Ram. Then problem has been fixed

Hello,
I use 64 bit linux version of Gambit 2.3.16. I manage to create a big mesh, say, more than 12-13 mln, but the error occurs when I try to convert it to .neu. And I use this format further with some in-house code. After completing meshing it starts to write the Neutral file, for example: ... "Writing 14046777nodes, 13600000 elements, 1 group and 0 bc sets to GAMBIT Neutral file test_new.neu. ERROR: Error writing to file at line 38008498 / Closing readfile ..." etc In the next message I attach a .jou file. You can run it from the command line as follows gambit -inp name.jou although I use alias: alias gambit='FLUENT_ARCH=lnx86 gambit -x11' I would be happy to any help since I fill uncomfortable to switch to another meshing tool. Thank you for help. Rustam |

No problem for me to export your *.neu file
It generates a 2.3GB file PS: I generates it from GUI >> File/Run Journal...

Hello All,
I want to do analysis of heat transfer from water flowing through pipes submerged inside concrete. I am modelling in GAMBIT and wish to analyse it on Ansys FLUENT. Can anybody help me out, how to model and simulate? Does any tutorials exist? |
