[deal.II] Re: Undefined Referece to `dealii::DataOut_DoFData<dealii::DoFHandler<2, 2>, 2, 2>::get_dataset_names[abi:cxx11]() const'

Thank you wolfgang, thank you Bruno. I appreciate your input! I did look through the settings of the cmake by running make VERBOSE=1. And I did notice that the compiler/linker that was running was v6 of gcc. In my IDE, it is running v4.9. A quick change to v6 was able to solve my issue On

Re: [deal.II] Re: Rescale dimensions of system before output

I.e. I should call the function like const std::vector locally_owned_vertices = get_locally_owned_vertices(triangulation); GridTools::transform (std::bind(::MinimalSurfaceProblem:: rescale_body_length, this, std::placeholders::_1), triangulation);

Re: [deal.II] Re: Rescale dimensions of system before output

Maxi Furthermore I tested the transform-function, and got the following error: > ~/heat_equation_with_pulse_propagation/heat_equation/source/main.cpp:1648: > 26: error: no matching function for call to ‘transform(std::_Bind_helper< > false, dealii::Point<2, double>

Re: [deal.II] Re: Rescale dimensions of system before output

The class has this member function, but it can not copy refined grids, thus making it unusable for me. Furthermore I tested the transform-function, and got the following error: ~/heat_equation_with_pulse_propagation/heat_equation/source/main.cpp:1648:26 : error: no matching function for call to

Re: [deal.II] There is something when I use cmake to configure dealii with hdf5

Thank you! Professor W. I have solved my problem, -DHDF5_LIBRARY=/usr/lib/x86_64-linux-gnu/hdf5/serial/lib this command should link a static library, not a /lib. 在 2018年4月27日星期五 UTC+8下午10:45:27，Wolfgang Bangerth写道： > > On 04/27/2018 01:28 AM, cxmai...@gmail.com wrote: > > @davydden But

Re: [deal.II] Re: Why fe.shape_value( const unsigned int i, const Point< dim > & p ) return a negative number?

Thanks a lot! I get the same answer by using quadrature.point(q), and I get the similar answer after I transfer the real space point into reference space( [0, 1]x[0, 1] ), and then use fe.shape_value(reference_point). Best Yidong 在 2018年5月7日星期一 UTC+8下午2:37:22，Wolfgang Bangerth写道： > > On

Thank you very much! My fe is FE_Q(1) type: FE_Q(1) I make comparison like this: 1.Create fe_values like this: FEValues fe_values(fe, quadrature, update_values | update_quadrature_points |
