	abstract = {A recent methodology utilised to simulate and synthesize physical models of complete
instrument geometries is extended to facilitate the implementation of larger physical 
models in real-time.
The existing system utilises explicit finite difference methods to simulate and
synthesize physical models of music instruments on Field Programmable Gate Array (FPGA) hardware.
To extend the computational abilities of the existing system, it is enhanced by more recent FPGA hardware
consisting of two FPGAs of the Virtex-7 family, a 2000T and a 690T which are
connected to a personal computer via a PCIe interface protocol.
A first implementation of a large scale geometry using explicit finite difference 
methods is compared to a specifically adapted pseudo-spectral implementation of 
a plate model, which is applied to simulate a geometrically correct model of a 
grand piano soundboard. 
A central interest of this work lies on the applicability to real-world problems arising 
in instrument acoustic research and instrument design. 
Thus, a dynamic configurability and contrallability of the models is sought after. 
To this end, an Input/Output protocol is utilised for real-time adaptability 
of the physical parameters of each model part. The simulation results of the soundboard 
model are compared to measurements taken on real grand piano soundboards in different 
production stages. },
