A modelling system ( 1 ) comprises a blood vessel simulating model ( 2 ) connected to a pump system ( 3 ) and mounted in the field of view of a polariscope system ( 4 ) and a camera system ( 7 ). The model ( 2 ) is mounted on an adjustable stand ( 5 ). The blood vessel simulating model ( 2 ) is connected to the pump system by outlet control and access valves ( 10 ). The blood vessel simulating model ( 2 ) is connected to the pump system ( 3 ) by a clip ( 9 ). A pressure sensor ( 8 ) is provided to monitor pressure levels within the model ( 2 ). The pump system ( 3 ), pressure sensor ( 8 ), polariscope ( 4 ) and camera ( 7 ) are controlled by controllers ( 39, 11, 13 ). The adjustable stand ( 5 ) is movable to facilitate rotation, change of orientation, change of level of one end of the model with respect to the other end, and bending of the blood vessel simulating model ( 2 ). The pump system ( 3 ) circulates a liquid to the model ( 2 ) to simulate blood flow in the model. The modelling system ( 1 ) facilitates determination of the magnitude and direction of the resultant pulsative forces acting on the model ( 2 ).
