I have a dimension independent code which can work for 1D, 2D and 3D. The
dimension of the problem is defined in the input file. Is there a way to
declare a constant integer variable (dim) for template?
for 1D
dim = 1;
for 2D
dim = 2;
else
dim = 3;
then,
FEM<dim> solid("parameters.prm");
solid.run();
The problem is that the <dim> template parameter is something the compiler
needs to know at compile time, but you want to only determine it at run time.
This doesn't easily work.
But you can do this with tricks -- take a look at the main() function of
ASPECT, for example:
https://github.com/geodynamics/aspect/blob/master/source/main.cc
lines 452-490.
