Hello everyone, I am trying to solve the "Propeller" problem and having this error when I am trying to run in parallel. The patch names in '0' and pollyMesh are same. I am not understanding where I am doing it wrong!!!

could anyone help me out with this!!!

Thank you!!!

Hello

the problelm is with your settings to the parallel solving


1/-if you want to use 6 core you have to change DecoposeParDict as follow:




object decomposeParDict;
}

numberOfSubdomains 6;

method scotch;

simpleCoeffs
{
n (3 2 1);
delta 0.001;

hierarchicalCoeffs
{
n (3 2 1);
delta 0.001;
order xyz;
}

metisCoeffs
{
}

manualCoeffs
{
dataFile "";
}

distributed no;

roots
(
);




Once you save the file you have to redecompose your case so you have to delete all the processor* files from your case .After that in the terminal run the command :



decomposPar


than you can run your solver like this :


mpirun -np 6 -yoursolver -parallel >log


hope this helps

Thank you so much!!!

so the values have to change according to the no of a core? if it I use 4 core the values should be (2 1 1) is that right?


simpleCoeffs
{
n (3 2 1);
delta 0.001;

hierarchicalCoeffs
{
n (3 2 1);
delta 0.001;
order xyz;
}

Hello,
you are welcome ,
In case you want to use 4 core you have to set :


numberOfSubdomains to be 4 like this : numberOfSubdomains 4;


and for the simpleCoeffs (i j 1) : the product of i and j must =4 ( i x j = numberof cores) and also please note that i and j must take integer values.
so it gonna be (2 2 1) or (4 1 1) as you like:


simpleCoeffs
{
n (2 2 1);
delta 0.001;

for the hierarchicalCoeffs you can leave it the way it is but me personally i always make it the same as simpleCoeff

hierarchicalCoeffs
{
n (2 2 1);
delta 0.001;
order xyz;


and to run in parallel you have to use :


mpirun -np 4 yoursolver -parallel >log


Hope this helps you
Take Care

Thank you so much!! It helps me a lot!!

One more error! While I'm running pimpleFoam solver to propeller Geo, the error displayed as

Unable to set source and traget faces?

What that mean have you come across such errors??

Thank you

Thank you

Not Really and without detailed error message i cant help that much

but i guess you need to :


1/-check your position (where you are launching the command in terminal) make sure that your case is in the run directory and that you are in your case folder

2/-check that your case folders are with there right names and that you didnt change anyof them by accident 0, constant, system ....
3/-other than that you can check your mesh i.e that you generated your mesh and that all of your files are there .and that you didnt modify anything bymistake

and than i guess you should be okk

Can you please go to this directory

srinath@srinath:~/OpenFOAM/srinath-6/run/propeller/stator
use the command

ls *

(there is blank space between ls and the * sign)


and send me see the results


also go the the directory constant/polyMesh and send me the list of the files in there

Hello,
From what i see it seem like all the files are there ,

Thank you so much!!

I have seen this post earlier but the thing is I did not understand the comment on that!!
Does the comment mean I have to change the axis of rotation? I have tried that option also but it did not work!!! I will do it again and I will post the comment!!

Can you please comment on my Geometry that I am currently working on, which is similar to this geo!!! my geometry has a rotating impeller which is used to mix the fluids(to get an idea it like a mixing tank but on the scale, it is small in size(7mm)). here the thing, I do not have any inlets or outlets to my Geo, all are considered as walls. when I am setting up the case file to this Geo! the patches which I have mentioned while I am meshing are(top, bottom, side and rotor). in the "0" folder the boundary conditions to my patches should be the same right. I am confused about what boundary condition should I used to those patches!! it is "NoSlip" or Wall condition. I am even more confused about the rotor patch!!!

could you please comment on it??

I tried to add an image of my Geo but it is asking the Url.


Thank you so much for your help.

Hello
I believe that from that post you need to check your Axe of rotation and that the center or rotation is well positionned ( maybe you changed that and forget about it or used a differetn geometry and kept the same for the previous Geometry )

2/-At this point i feel kinda going blind and i may not help you that much.
Even though am really busy but i guess it would be better if you can send me your case file i'll try to have a look at it on Saturday and let you know what i find (i ll do my best to help you ).

Hope this helps
Kind regards
