simplex meshes in deal.II

[y choi]

Dear Deal.II community,

I'm programming with tetrahedral mesh input using simplex meshes.

In step-3,

FE_Q<2> fe;

-> MappingFE<2> mapping;

   FE_SimplexP<2> fe;

   mapping(FE_SimplexP<2>(1))

   ...

(https://www.dealii.org/current/doxygen/deal.II/group__simplex.html)

I think, FE_Q<> in step-3 tutorial can be replaced like this.

But I don't know how to change the code in step-8 tutorial.

In step-8,

FESystem<dim> fe;

fe(FE_Q<dim>(1), dim)

-> ???

Thanks,

yyyychoi

FE_SimplexP should be what you are looking for instead of FE_Q.
