Hi,

Working in parallel with the 6.3.26 version of Fluent-t8, with a mesh of 7,000,000 elements, read the mesh and perform the setting of the simulation correctly, but to make the run (iterations) do not work the 8 cores and takes so much!

Someone pass the same? to that is the error?

I hope their views

Thank you very much

It maybe you are not using parallel processing. try this: right click on fluent desktop icon, on the fluent path add -tn (n=no of processor in CPU, e.g. -t2). for my computer it's
C:\Fluent.Inc\ntbin\ntx86\fluent.exe -r6.3.26 2d -t3
you should insert this address
C:\Fluent.Inc\ntbin\ntx86\fluent.exe -r6.3.26 2d -t8
If you are modeling 3d insert 3d

Do you have academic license? Those have restrictions about number of nodes you could use.

Are you using any UDF?

Thanks for the reply flow_CH.

Now I have the commands as you propose: C: \ Fluent.Inc \ ntbin \ win64 \ fluent.exe 3d-t8-r6.3.26

In fact, I made ​​the partition in 8 correctly, starts with FMG perfect, but when iterating cores do not work.

Any other ideas?

Vasava: not an academic license should not have size limitation problem and do not use a UDF.
In addition, some upper size models working properly.

Any other ideas?

The model is of a complete vehicle, with ground and rolling wheels. It has two "porous volumes" that model the radiators.
