Thanks for the answer but didnt worked here.
First I tried
ExodusII_IO::set_output_variables("c")
ExodusII_IO(mesh).write_equation_systems (file_name.str(),eq_sys);
That gave me this error:
angiogenesis.C: In function 'int main(int, char**)':
angiogenesis.C:339:47: error: no matching function for call to
'libMesh::ExodusII_IO::set_output_variables(const char [9])'
angiogenesis.C:339:47: note: candidate is:
In file included from angiogenesis.C:44:0:
/usr/local/include/libmesh/exodusII_io.h:158:8: note: void
libMesh::ExodusII_IO::set_output_variables(const
std::vector<std::basic_string<char> >&)
/usr/local/include/libmesh/exodusII_io.h:158:8: note: no known
conversion for argument 1 from 'const char [9]' to 'const
std::vector<std::basic_string<char> >&'
angiogenesis.C:340:3: error: expected ';' before 'ExodusII_IO'
Than I tried
std::vector<std::basic_string<char> > out_var;
out_var.push_back("c");
ExodusII_IO::set_output_variables(out_var);
ExodusII_IO(mesh).write_equation_systems (file_name.str(),eq_sys);
and got
angiogenesis.C: In function 'int main(int, char**)':
angiogenesis.C:339:44: error: cannot call member function 'void
libMesh::ExodusII_IO::set_output_variables(const
std::vector<std::basic_string<char> >&)' without object
And also did:
std::vector<std::basic_string<char> > out_var;
out_var.push_back("v0_tumor");
ExodusII_IO(mesh).set_output_variables(out_var);
ExodusII_IO(mesh).write_equation_systems (file_name.str(),eq_sys);
Which was OK to compile but when running gave me:
Error closing Exodus file.

terminate called after throwing an instance of 'libMesh::LogicError'
what(): Error in libMesh internal logic
Any ideas?
Thanks again
