I'm new user of NX Simcenter Thermal/Flow. To accelerate the simulation/calculation time of a coupled thermal-Flow 3D model by using Advanced Thermal-Flow, i want to activate the "Run solution in Parallel". However, there is an error as below:
Available nx Thermal/Flow parallel processing capabilities:
- Thermal Solver Parallel = Yes
- Flow Solver Parallel = Yes
Using MPI installation from
"C:\Program Files\Siemens\Simcenter 11.0\nxcae_extras\tmg/mpich2"
Traceback (most recent call last):
File "MPIvalidate.py", line 1451, in <module>
File "MPIvalidate.py", line 762, in TestMpirunIOPermissionsWindows
File "MPIvalidate.py", line 370, in CommandsGetOutputErr
UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe8 in position 98: invalid continuation byte
Failed to execute script MPIvalidate
I tried to follow the instruction by installing the mpich2 as described without success.
Does anyone have the solution ? It would be very hepful for me.
Solved! Go to Solution.
It is not possible to have the smpd running in task manager. Do you know how to do it
What i tried:
* smpd -stop
* smpd -start
* smpd -install
But it doesn't work !
There are two possibilites:
Does this happen on all models or just this one?
I would also suggest using the latest solver patch, if you haven't already installed it. You can get the latest patch from the GTACwebsite.
If not solved yet, or maybe for others, have also a look at the following FAQ, it has some options you can check.
Thanks Dennis for your clear solution.
Finally, i have managed to activate this kind of parallel calculation. As said Zouya_Z, i tried to update the Thermal/Flow solver by getting the latest version (11.0.8 of march 7th). It works very well.
Many thanks for your exchange
