Member Function Documentation

◆ CreateContactMaterials()

void chrono::vehicle::fmtv::FMTV_ChassisFront::CreateContactMaterials ( ChContactMethod contact_method )

overrideprotectedvirtual

Load contact materials.

A derived class must implement this only if it sets m_has_collision to 'true' and should use contact materials consistent with the specified contact method.

Reimplemented from chrono::vehicle::ChRigidChassis.

◆ GetLocalDriverCoordsys()

virtual ChCoordsys chrono::vehicle::fmtv::FMTV_ChassisFront::GetLocalDriverCoordsys ( ) const

inlineoverridevirtual

Get the local driver position and orientation.

This is a coordinate system relative to the chassis reference frame.

Implements chrono::vehicle::ChChassis.

The documentation for this class was generated from the following files:

/builds/uwsbel/chrono/src/chrono_models/vehicle/mtv/FMTV_ChassisFront.h
/builds/uwsbel/chrono/src/chrono_models/vehicle/mtv/FMTV_ChassisFront.cpp
