How to interpolate values in probesDict
 

Hello everyone,

I would like to know how can we use a interpolation scheme in probesDict. Currently i use probes utility to extract velocitiy component inside a cylinder. My probes location are placed at a equal distance of 1mm inside the cylinder. And i have like around 1000 location inside the calinder. The problem i face now is, The cell size in the volume mesh are large and at some location two prob point are at the same cell. Due to this i have two prob with the same velocity values. I belive these values are not interpolated and the same cell values are writen for both the probe location. I learnt from http://www.cfd-online.com/Forums/ope...tml#post574910 that we can use interpolation schems in probes dict. I would like to know from any one who can post a syntx, about how can we use a interpolation schemes in probesDict.

#Note: My problem is same like http://www.cfd-online.com/Forums/sta...same-cell.html this thread. But i am using probes utility in openfoam. And the values are not interpolated.

Thanks,
Dinesh

hello!

you can add the following line in your probesDict file:
interpolationScheme cellPointFace;


You can find more information at:

Hi Stathis,

Can I use the interpolationScheme syntax in controlDict as well?

Hi Yeru,

Yes, you can.
You can add something like this to your controlDict:

Morning Stathis,

Thanks for that, can I do the same thing for probes in controlDict?

Sure, it's applicable to probes as well.

Kind regards,
