User Story 100505: Implement performance enhancements for GPU ray-tracing

Fixed versions: 2412.2

Several enhancements were made to the GPU ray-tracing algorithm to boost model performance. While these code changes had minimal impact on the results, they did improve overall solve times. For Simcenter 3D 2412, users are advised to use solver version 2412.2 or higher when GPU ray-tracing computations are enabled.

Bug 101766: Correction for rotational effects in thermal convecting zone loads does not consistently apply the appropriate convective area on an internal line between two elements of different thickness

Fixed versions: 2412.3, 2406.8

The correction for rotational effects in the thermal convecting zone load did not use the appropriate convective area when adding the source term to the solved energy equation. This issue arose when the thermal convecting zone was applied on an internal line between two plane stress elements of different thickness or between a plane stress and an axisymmetric element, resulting in inaccurate solid temperature predictions at those locations. After the fix, the temperature results are now consistent with those obtained using other boundary conditions that model the same physics under similar conditions, for example, with a convection coupling simulation object.
