But since there are two choices for which diagonal to draw, two different ways of dividing the cell in half, both diagonals are used and the interpolated values found with each diagonal are averaged to compute the final result. The triangle that encloses the point is identified and the values are interpolated as for triangles.

Compute the weighted average to calculate the probe results.įor ordered and quadrilateral cells the enclosing quadrilateral is divided in half by drawing a diagonal line between opposite points resulting in two triangles. Having problem in Tecplot 360, movie: saeedi: Main CFD Forum: 6: J14:13: Incorrect showing for the contour in Tecplot 360: bhbuaa: Tecplot: 0: Aug12:46: How to plot contour lines in Tecplot 360 using Excel file: Iqbal: Tecplot: 1: 19:22: Streamlines under Moving reference frame Spiral streamline from. Determine the weighting to give each of the three corners of the triangle.3. Determine the triangle that encloses the chosen point.Ģ. For triangular cells, this is a straightforward interpolation of the three nodal values of the triangle that encloses the point:1. In two dimensions Tecplot interpolates for dataset values at the chosen point using bilinear interpolation.

What process does Tecplot use for probing? Also for streamtrace placement contour labeling linear interpolation and polyline extraction in 2D. < Back 2D Probe calculation Calculation, Tecplot 360 September 24, 2009
