I need to do time dependent heat equation
with Polynomial Coefficient for c parameter.
I put fuction c=A0+A1*u+A2*u^2+A3*u^2
It is one dim problem
In the beggining temperature is constant for whole interval.
Temperature goes smaller at left end of the interval
There is also constat emission coefficient at the left end.
Ideal termal insulation is on right end.
Simulated Time is 2 days.
Mesh is extra fine.
In stead of proper solution I receive singularity error.
How can I overcome this error? What could be reasons that I receive it?
Regards
Marek
