Run a half-car model as a full car¶

Convert Half Car to Full Car mirrors a half-car model when the case is created, so you can upload and maintain one side of the car and still run a full-car simulation, for example at yaw.

Before you start

Your Account needs the Convert Half-Car feature. Without it, the option isn't shown. Contact support@bramblecfd.com to have it enabled for your Account.
The geometry should be the left-hand side of the car, with left-hand side tokens (lh, lhs, LH, LHS) in the zone names.

Turn it on¶

Open the Run and go to the CFD Setup tab.
Click the edit icon next to an Attitude's name.
In CFD Attitude Setup, tick Convert Half Car to Full Car.
Click Save, or choose Save to All from the Save menu.

The Convert Half Car to Full Car row on the CFD Setup tab shows ✓ or ✗ for each Attitude.

What Bramble does¶

When the case is created, Bramble:

mirrors the Parts about y = 0, before the kinematics are applied, so steering and wheel movement apply to both sides
mirrors the Template Case's components, domain, exports and monitors, and extends the domain across y = 0
renames each mirrored zone from left to right, for example fr-wh-rim-lhs → fr-wh-rim-rhs
reports forces for the full car

The side tokens are read as described in side tokens.

If a zone can't be renamed safely, case creation fails with "Cannot safely rename the reflected zone <zone> of part <number>". This can happen when a side token also appears inside another zone name. Rename the zones and upload the Part again.

The Template Case¶

An Attitude whose Template Case has Half Domain turned on is tagged Half Domain, unless Convert Half Car to Full Car is ticked. A converted Attitude isn't tagged, so post-processing treats it as a full car.
