Simulation Health warnings form will cause a crash if used with Dry Weather Flow Phase.

2025.5

Resolved in 2026.0

Sump Depth, when added to Manholes, is not considered in the 1D or 1D-2D analysis of the design.

No workaround available.

2025 (all versions)

2024 (all versions)

2023 (all versions)

Resolved in 2026.0

In the Entry Loss Audit Report, the angle displayed in the results table is the supplementary angle of the flow deflection, instead of the angle that the flow is deflected by.

Workaround - Users can reverse the table by entering the supplementary angles and modifying the entry loss values as required.
Note: This workaround is not valid for outgoing connections that have multiple incoming connections.

2025 (all versions)

2024 (all versions)

2023 (all versions)

Resolved in 2026.0

Open in all versions of 2025, 2024, and 2023.

If users create a template for Flexible Reporting in InfoDrainage 2025.3 and then attempts to load this template in versions 2025.1 or 2025.2, it might cause a crash.

This is due the attribute "Name" that was introduced in 2025.3 for Inflows. As this property did not exist in versions 2025.1 and 2025.2 it causes a crash.

Workaround - Users can upgrade to InfoDrainage 2025.3 or they can also exclude this property from their templates.

2025.2

2025.1

Resolved in 2025.3
