Hello,

I'm using Openfoam v1806+.

I created the motion for the fish undulation, and completed the motion itself, but I wanted to load the forces acting on the surface of the model into the motion program as well.

( I used this site as a reference for motion creation.

http://www.tfd.chalmers.se/~hani/kurser/OS_CFD/

"make a fish swim")


There is a sentence in the program to get the coordinates of the surface to be analyzed target as shown below.(This is an excerpt from line42 of the attached file)

const pointPatch& p,
const DimensionedFields<vector,pointMesh>& iF

fixedValuePointPathFields<vector>(p,iF),

p0_(p.localPoints())


I interpret that "p" and "iF" get the mesh information, and "localPoints()" gets the coordinates of each surface point.

I would like to know a function like this "localPoints()" that would get the preessure acting on the surface of the analysis target.


I would like to know if anyone knows anything about this.


Thank you.

Hi Hiroaki,

Have you found a solution? In that case, can u post it?

Else, currently, what I did is:

1. I filter the forces output file to something simpler
2. read in that file to get the forces req

It works but it's slower.
