design_xxxxVolumeFlowStandard for all inlets and outlets of all components.
- #1910 Fixed bug where coils could not be calculated in exhaust only units.
- #1851 Rotor calculations has new table
dll_rotor_exchanger_casing_size. If this table has non-zero values the wheel casing will be fixed. Otherwise the smallest casing size for the given wheel diameter is used. If casing size is defined but wheel diameter is not set, the wheel diameter will be the largest given the casing size. If neither rotor or wheel casing size is given the largest wheel which fits the casing will be selected.
- #1753 Systemair Coils 1.0.0.0-v6 now integrated for fluid/DX/Cond calculations.
- #1892 Moved
exhaust_airflow perf case input to extract_airflow, as it is the flow through the ventilated area that the user want to define.
- #1849 Added
Use actual volume flow input to performance cases. When this option is selected, the air flow inputs will use density at defined atmospheric pressure and 20 C. We have also added a new specifications:
design_xxxVolumeFlowAtmospheric: Volume flow given density at atmospheric pressure and 20 C.design_xxxRelativePressure: Pressure relative to atmospheric pressure.
- #1896 Aircalc classic silencers updated from 1.0.0.0-v3 to 3.20.243-v1. The custom_data files are copied from 1.0.0.0-v3 to 3.20.243-v1.

- ✅ casing_panel_property_division
When a panel is temporarily split during vertical panel merge of compact casings properties to can be assigned to the slices.
Example: K1 has the properties mergablestart=0;mergableend=0.
mergableend=1 is assigned to properties_from and mergableend=1 is assigned to properties_to.
