This example creates an activation sequence for use in a forward problem. The original activation sequence was created using a single region, tricubic Hermite FEM mesh and solved for an Eikonal equation (refer PhD Thesis - K Tomlinson). This activation sequence has been transformed, orthoganally projected onto a 3 region BEM bi-linear mesh and fitted. This provides a smooth activation sequence on a mesh with different geometric shape and properties.

The activation map can be visualised with draw.com.
