Bug 125848: Unexpected temperature results on a plane stress-axisymmetric internal line in a model with enclosure radiation involving an axisymmetric edge, a plane stress edge, and a plane stress-axisymmetric internal line that uses the Monte Carlo method

A regression affecting enclosure radiation requests using the Monte Carlo method was introduced with solver versions 2406.12, 2412.8, and 2506.0. In models containing plane stress-axisymmetric internal lines connected to axisymmetric and plane stress edges, temperature results could be inaccurate due to missing view factors in the generated VUFF file. This issue has been resolved, restoring the expected temperature distribution.
