printing a VectorArrayCoefficient

[gokhalen]

Is there a way to print out what is in f after line 152 has been executed?

mfem/examples/ex2.cpp

Line 152 in ff7ed2e

f.Set(dim-1, new PWConstCoefficient(pull_force));

There is no direct way to print a Coefficient object, but you can project it on a GridFunction and print that.

For example:

   {
      // Project the coefficient `f` onto the GridFunction `x`
      GridFunction x(fespace);
      x.ProjectCoefficient(f);

      // Visualize `x` with GLVis
      socketstream sol_sock("localhost", 19916);
      sol_sock.precision(8);
      sol_sock << "solution\n" << *mesh << x << flush;
   }
