Summary | 0001235: triSurface sample: Use point values instead of interpolation from face centres | ||||
Description | The surface sample of type sampledTriSurfaceMesh samples the field values on the face centres of the triSurfaceMesh. This works well if the triangles have a low aspect ratio and the distances between the face centre and the points are nearly equal. But if the aspect ratio is very high, the distances are very different. This leads to good sampling values for the points near to the centre, but very bad values for the triangle points which are far away from the centre. The interpolation option finally makes the sampling very inaccurate. Instead of interpolating point values from cell values it would be better to sample point values directly. I have attached screen shots, which show the results of the different sampling methods. | ||||
