End of solution stage.

This run of the ANSYS CFX Solver has finished.
I set up my CFX-pre file as a parallel run, but it send out this error. one time it didn't start to solve. it doesnt send out any error in serial run, what can i do? i want to use all my 24 processors...

Have you confirmed your multiprocessor setup works for simple simulations? Have you run a simple simulation like the Benchmark.def or a tutorial example on multiprocessor?

Hi! what is the multiprocessor setup? what i have to do to confirm it? Ive simply choosed the first of parallel solving and then run it, sometimes it doesnt start to run and sometimes it encounters with above error... :(

Read the documentation section about setting up parallel simulations. It describes what you must do.

Ive set everything according to the help ... It just starts to prepare but stays at solving section :(

Do the simple tutorial simulations run? <CFX_ROOT>/examples/Benchmark.def is a good one to try.

it doesn't solve simple tutorials as well... what i have to do? isn't the software installed properly? Ive read in other post it may work with LAN connection, whats your idea?

Do you have 24 hpc licenses or 2 hpc pack licenses? You can't just solve on 24 processors without the parallel licenses.

Hi friends,
Thanks for your supportive responses... I finally find out why the software doesn't solve in parallel mode, It was because out network adapter didn't work (disables). I just connected the PC to others in Lab and then It ran...
Many many thanks....
