« on: July 11, 2012, 06:26:35 PM »

I get the following when I load the case and data file:

999999 (..\src\mpsystem.c@1149): mpt_read: failed: errno = 10054

999999: mpt_read: error: read failed trying to read 4 bytes: No such file or directory
MPI Application rank 0 exited before MPI_Finalize() with status -1073741819
 The Parallel FLUENT process could not be started.


Can any one give suggestion?

Thanks.

Fluent / VOF to model draining tank, swirling fluid, vortex?

« on: May 13, 2012, 11:16:43 AM »

Hi,

It is possible to model a draining tank filled with a swirling liquid, and to capture the vortex that forms at the drain. The goal is to pinpoint the time at which the first gas reaches the drain.

Please help.

Thanks.
