6.9.31.1 thickness (real)[optional]
Specifies the medium thickness (in units of length) where a foil model is intended. This is
the critical parameter in determining the effect on particles passing through the foil, rather
than by any dimensions specified for an object (usually one cell thick) in the [Objects]
section that is associated with the foil model. For boundaries where one just wants to
compute the surface temperature rise, one can use an arbitrarily large value. Present only
for a DENSE medium.
