I create an interpolator using the below command:


I am guessing that a change in U_ will be taken into account, but
will the point/node values be updated when U_ changes, or do I have to remove and create the interpolator at every timestep?

If so, is there a way to only update the point values, so I do not have to recreate the interpolator for every timestep?

Hello Rasmus,

You indeed need to remove and create the interpolator at every time step. It is cheap to construct though. It is the point interpolate of the U_ field so needs to change every time U_ changes.

The volPointInterpolation_ can stay; it holds only the geometric weighing factors which are constant provided your mesh is not moving.


p.s. saw your hour-glass animation. Very impressive.
