Description
Running KRC cases with layering (see Material Properties and Regolith Layering for more information on layering), scenarios can be encountered where thin layers are desired. When sufficiently thin layers are encountered, the time step requirement can be very small and KRC will fail to run. In order to bypass this, we can enforce a smaller time step using the 'N2' field.
The below examples are relevant to the case found in the thin.pdf (page 10) within directory /doc.
Examples
For the following examples, we consider a case where a lower-TI "dust-like" layer (50 J m^-2 K^-1 s^-1/2) overlies a higher-TI layer (250 J m^-2 K^-1 s^-1/2).
