Unfortunately, the CellNet Generator was not designed to be used in such a way (and changing it to allow it to do so would be quite difficult).

Thanks very much for your quick response - I thought it might not be possible.

In which case, I'm looking for documentation on how GoldSim calculates diffusive area and diffusive lengths (found in each of the generated cells). I understand the principals of each of the terms and could calculate these in simple cases, however, the situation I'm trying to understand is more complicated (uneven discretisation across diffusion pathways). Do you please know of any documentation (if possible showing the formulas).

• Rick Kossik

Create a Cell Net in a model, and then view the Cell Net directly in GoldSim.  You will see all of the equations for areas and lengths directly in the Cells.

Sorry, I can't find the equations. I've created a Cell Net and also automatically generated cells. When I click on a particular cell, click on the diffusive fluxes tab, and look for example, at a diffusive area, all I see is the current value (no formula). Where do I find the equation for diffusive area on the CellNet?

Thanks

For planar geometry, each Cell represents a rectangular prism, and the area is the rectangular area of the side through which diffusion is taking place.  For cylindrical geometry, each Cell represents a cylindrical shell.  The area is the area of the outer cylinder defining that shell.

The diffusive length is always from the middle of the Cell to the edge of the Cell (the edge where the area is defined).

Thanks. I'm having difficulty understanding how GoldSim has calculated a particular cell network. Please can you help? In my model, I have unequal discretisation of cells across a boundary. For example, I have three cells on the left side, and have one cell on the right which is the same height as all of the three cell heights on the left combined. The geometry is planar. How would GoldSim then have computed the diffusion areas?

As I commented above, for planar geometry, each Cell represents a rectangular prism, and the area is the rectangular area of the side through which diffusion is taking place. Send me a model with just the Cell Net Generator and I will explain
