Example f613: Adding fibres

This example defines fibres on the bladder and explains the components of the fibre field.

The fibres in the majority of the bladder, are oriented in a consistent pattern, the exception being in the trigone region (posterior inner surface). There are inner and outer longitudinal layers and a circular intermediate layer. It is also recognised that there is also considerable overlap between the layers adding stability. The wall of the CMISS bladder model is two elements thick to allow the fibres to be described by a linear variation. The fibres are arranged from an outer longitudinal layer to an intermediate circular arrangement and back to an inner longitudinal layer.

The fibres in the trigone region are distinct from the rest of the bladder. They run longitudinally from the internal sphincter up the inner posterior wall of the bladder and diverge to be continuous with the ureters.

Figures 1a and 1b show the of the intermediate circular layer and the inner longitudinal layer respectively of the bladder and trigone.

The fibres are defined by running the cmiss example.
