Interpolation for lagrangian particle

vkoppejan · March 5, 2017, 11:12

Hi All,

There's a number of topics on interpolation but I can't seem to find what I want.

I want to interpolate a scalarField or vectorField to a single particle position.

So given p.position() and <some>Field

Return <some>Field (example fvc::grad(p) ) interpolated at p.position().

Thanks in advance for your help.

Cheers,

Victor

Have a look in

src/lagrangian/intermediate/submodels/Kinematic/ParticleForces/PressureGradient/

There a Interpolator is used, just like you want it.
