Function Documentation
◆ AttachAssembly()
template<typename ScalarType >
| void chrono::modal::ChModalVisualSystemIrrlicht< ScalarType >::AttachAssembly | ( | const ChAssembly & | assembly, |
| const ChMatrixDynamic< ScalarType > & | eigvects, | ||
| const ChVectorDynamic< double > & | freq | ||
| ) |
Attach the assembly to be visualized.
This function must be called before starting the simulation loop. The eigenvectors and frequencies must be provided, typically through ChModalSolverUndamped or ChModalSolverDamped.
◆ SetAmplitude()
template<typename ScalarType >
| void chrono::modal::ChModalVisualSystemIrrlicht< ScalarType >::SetAmplitude | ( | double | amplitude | ) |
Set the amplitude of the mode shape animation.
Eigenvectors are normalized and then multiplied by this amplitude.
◆ SetFixedFrequency()
template<typename ScalarType >
| void chrono::modal::ChModalVisualSystemIrrlicht< ScalarType >::SetFixedFrequency | ( | bool | val | ) |
Fix the frequency of the mode shape animation.
The frequency is then fixed to 1 Hz. This is useful to visualize the mode shape without the frequency effect. The speed factor is still applied.
◆ SetMode()
template<typename ScalarType >
| void chrono::modal::ChModalVisualSystemIrrlicht< ScalarType >::SetMode | ( | int | mode | ) |
Set the mode to be visualized.
The mode is specified as a 1-based index.
◆ SetSpeedFactor()
template<typename ScalarType >
| void chrono::modal::ChModalVisualSystemIrrlicht< ScalarType >::SetSpeedFactor | ( | double | speed_factor | ) |
Set the speed factor of the mode shape animation.
The frequency is multiplied by this factor.
