Initial conditions

Setup tree: Initial conditions
Controls
Method
Initialise
- Control: choice (
ComboRow) - Default:
Uniform - Bound to:
CaseState.initMethod - Options:
Uniform,Potential flow,From an existing run - Writes:
potentialFoam (U only),potentialFoam -writephi,0/* internalField - Shown when:
root.wholePage
Source case
- Control: value (
ValueField) - Default: empty
- Bound to:
CaseState.initMapSource - Value modes: none (plain entry)
- Shown when:
root.wholePage && CaseState.initMethod === "From an existing run"
The case directory to map from. Its latest time is used.
Use this case's own run
- Control: action (
ToolButton2) - Enabled when:
CaseState.runDirectory !== ""
Track the inlet
- Control: on/off (
ToggleRow) - Default:
true - Bound to:
CaseState.initFromInlet - Shown when:
root.wholePage
Seed the domain with the inlet's velocity and turbulence, so changing the inlet keeps the initial field consistent.
Values
Velocity
- Control: value (
ValueField) - Unit: m/s
- Bound to:
CaseState.effectiveInitVelocity - Writes:
0/U internalField - Shown when:
root.showsField("U")
Pressure
- Control: value (
ValueField) - Unit: Pa
- Default:
0 - Bound to:
CaseState.initPressure - Writes:
0/p … m²/s² (kinematic) - Shown when:
root.wholePage || root.fieldFilter === "p" || root.fieldFilter === "p_rgh"
Temperature
- Control: value (
ValueField) - Unit: K
- Default:
293.15 - Bound to:
CaseState.initTemperature - Writes:
0/T internalField - Shown when:
CaseState.energyEnabled && root.showsField("T")
Turbulence
Intensity
- Control: value (
ValueField) - Unit: %
- Bound to:
CaseState.effectiveInitIntensity - Shown when:
CaseState.turbulenceFields.length > 1 && root.turbulencePage
Length scale
- Control: value (
ValueField) - Unit: m
- Bound to:
CaseState.effectiveInitLengthScale - Shown when:
CaseState.turbulenceFields.length > 1 && root.turbulencePage

+ Add subdomain
Label changes with the case; the source gives these forms: + Add subdomain, + Add subdomain of ….
- Control: action (
ToolButton2)
Conditional and repeated groups
Per item in CaseState.initRegions
repeated once for every entry in CaseState.initRegions
Shape
- Control: choice (
ComboRow) - Default:
box - Options:
box,sphere - Writes:
setFieldsDict/regions - Shown when:
!regionCard.usesPrimitive
Field
- Control: choice (
ComboRow)
Which field setFields writes here. Changing it moves this subdomain under that field in the tree.
Value
- Control: value (
ValueField) - Default:
1 - Value modes: none (plain entry)
A bare number for a scalar, or (x y z) for a vector — which keyword setFields needs depends on it.

Problems reported against this step
The application reports no problems against this step.
… marks a value the application computes at run time, so the source carries no fixed text for it.
