Minutes 6 November 2006

Present: Jagir, Travis, Karl, Shane, Marc.

Different operating systems.

• Shane has libMesh working with Cygwin on bioeng126 but not working with Ehsan's system.
• Shane at the same stage with cvs libmesh as with 0.5.0. Built on AIX with XL compiler but aborts.

CellML

• Jagir has some modifications to Andrew's CCGS to make a C++ class.
• First example can use generated code from this.
• When modifications are incorporated in CCGS, we can have the Makefile run Andrew's executable to generate the code from CellML source.
• Will need to consider sharing data between cells where possible.

Marc Jacobs

• Modelling fluxes in tissue, particularly the eye.
• Continuum model at different levels.
• Will have other students also doing modelling.
• Wants this done on a platform with some sort of longevity.
• Huge difference in spatial scales between within cells and in extracellular space.

Spatially varying Material parameters

• Two options:
  • MeshData
    • Defines values at nodes and in elements but doesn't define how to interpolate the data.
  • System variables
    • Provides different interpolations with the parameters.
    • Seems more widely used than MeshData.
    • Need to investigate how the information is stored in files.
• System variables seems more appealing if file formats are suitable.

Fibre angles

• Need to translate fibre Euler angles into rotation matrices.
