Minutes 16 October 2006

Present: Travis, Jagir, Karl, Ehsan.

Ehsan is modelling transport of solutes in the eye.

• Includes: fluid flow with osmotic gradients, diffusion, conduction.
• Unknowns: concentrations, fluid velocities, electrical potential.
• Looks like this has been considered from a finite-volume bidomain perspective.
• Could probably be done with finite elements. Is this better?

Boundary conditions

• Travis using normal Dirichlet boundary condtions where a column and row are replaced with those from the Identity and a contribution is made to the rhs.
  • Looks like DenseMatrix::condense may be useful here.

libMesh solution variables

• 3 possibilities
  • local unknowns: System.solution
  • local unknowns + "ghost" unknowns: System.current_local_solution
  • all unknowns: ??
• When are vectors updated from other vectors.
  • current_local_solution is updated automatically from solution in ImplicitSystem::solve.

KDevelop

• Jagir and Ehsan have been looking at using KDevelop for writing code to use LibMesh.
  • But KDevelop seems to use autotools to write a Makefile.
    • Can this be turned off?
    • Or where can the libMesh library location be specified?
