Hi,
yes, for isoheat material this is possible. The conductivity and capacity can be functions of temperature and time.
The input can have following form:
* simple double (constant) value,
* simple expression, that is evaluated by internal parser and that can depend on any number of variables, which are defined by calling context (in your case you can use 't' for time and 'te' for actual temperature).
* reference to a function, defined in input file and maintained by corresponding Domain.
The scalar functions can replace constant variables in many places. The advantage is that they are naturally supported by
input readers (simple values are formatted as usual, simple expressions are enclosed in '$', references to external functions
are formatted as @i, where i is the number of corresponding external function).
For an example, refer to tmpatch46.in (uses external function)
