Smoothing tri-meshes

Use the Smooth Surface (prepare > Post-Processing Tools > Tri-mesh Tools > Smoothing) form to reduce the number of spikes in tri-meshes. Other smoothing options, including refining surfaces and reducing nodes, are also available.

To use the tool:

1. From the Source drop-down list, select the source that contains the tri-mesh that you want to smooth. All the available tri-meshes in the selected source are listed in the table below.
2. Select the checkboxes next to the tri-meshes you want to smooth.

3. Select the smooth mode.

   2D projection  Select '2D projection' to remove any spikes from your data.

   Node average  Select 'Node average' to make the angles of the tri-meshes more equally distributed. This is required in geomechanical modeling.

4. Select smoothing options:

   Resample tri-mesh  Removes all original nodes and triangles and a regular spaced tri-mesh representation replaces the original surface.

   Keep original boundary  Retains the original tri-mesh boundary in the resampled tri-mesh.

   Keep watertight connections  Retains associated locked nodes at surface intersections in the resampled tri-mesh.

   Smoothness (Less - More)  Use the slider to find the proper range. The entry field next to the slider is updated accordingly, with a (reference) value between 0 and 100. You can use this value if you want to apply the exact same settings in another iteration. Internally, the tri-meshes are projected and resampled, and after this resampling a median filter is applied. When you choose the ‘less’ option, a high resolution resampling is applied, therefore only moderate smoothing will be applied.

5. To smooth the tri-meshes, click OK or Apply.
