• Visualization of higher entities of edges shows that in the interior of the piece some surfaces are isolated.
• Press ESC to finish higher entities visualization.
• To generate a conformal mesh, first execute a global collapse of the model.
• The GiD collapse depends upon the Import tolerance. Two entities are collapsed (converted into one) when they are separated by a distance less than the Import tolerance parameter. To test this, enter a new value for the Import tolerance parameter.
• Go to Utilities->Preferences, and select Import and Export branch. Set the Import tolerance to User define value and enter 0.15 for the Value of import tolerance. Click Apply.
