User Story 89556: Produce a fatal error when an Enclosure Radiation simulation object is applied on an internal line between two plane stress meshes

Fixed versions: 2406.4, 2312.8

An enclosure radiation applied on an internal line between two plane stress meshes, including hole and bolt types, is not supported. The thermal solver now produces an appropriate fatal error message. Results obtained with previous solver versions for such a scenario are incorrect.

Bug 90107: Incorrect total absolute fluid temperature on walls output results when the 'Activate Rotating Machinery Options' toggle is disabled

Fixed versions: 2406.4

The elemental and nodal results for total absolute fluid temperature on walls were incorrectly computed for boundary conditions with the Activate Rotating Machinery Options check box cleared. This behaviour was a consequence of badly initialized variables in the thermal solver. This has been fixed.

Bug 90156: Results for fluid pressure on walls are partially displayed over a part of a single boundary condition selection where the defined heat transfer coefficient is zero

Fixed versions: 2406.4, 2312.8

Prior to the fix, the elemental and nodal results for fluid pressure on walls were only displayed in post-processing for elements having a non-zero heat transfer coefficient value. After the fix, the results for fluid pressure on walls are not disabled based on the heat transient coefficient value unless overlapping boundary conditions are present. Thus, for single non-overlapping boundary conditions where the defined heat transient coefficient is zero, the results for fluid pressure on walls now look continuous.

Bug 92273: When streams on faces are applied using the relative temperature reference frame, the radius on the walls needs to be considered when computing the total temperatures as is done for streams on edges

With the relative temperature reference frame specified, a generic or cylindrical two-sided thermal stream on faces load produced incorrect total absolute/relative fluid temperature results. The thermal solver did not account for the wall radius. For this scenario, a mismatch was evident when comparing results to an equivalent 2D axisymmetric model using a two-sided thermal stream on edges load. This has been fixed.

User Story 96318: When one-sided cylindrical streams on faces are applied using the relative temperature reference frame, the radius on the walls needs to be considered when computing the total temperatures

With the relative temperature reference frame specified, a cylindrical one-sided thermal stream on faces load produced incorrect total absolute/relative fluid temperature results. The thermal solver did not account for the wall radius. This has been fixed.
