My main.cpp code is: // main.cpp #include <LibUtilities/BasicUtils/SessionReader.h> #include <iostream> using namespace Nektar; int main(int argc, char* argv[]) { LibUtilities::SessionReaderSharedPtr session = LibUtilities::SessionReader::CreateInstance(argc, argv); std::cout << "Session Name: " << session->GetSessionName() << std::endl; std::cout << "Parameter TimeStep: " << session->GetParameter("TimeStep") << std::endl; return 0; } The main.cpp code can be compiled successfully, but when I run the executive with a session file (eg., ./main ChanFlow_3DH1D_FFT.xml),the method GetParameter produce an error saying the parameter "TimeStep" cannot be found, which actually exists in the session XML file. Could you give me some suggestions about what went wrong here? The required files (main.cpp, CMakeLists.txt, ChanFlow_3DH1D_FFT.xml) are attached in attachments. Thanks, Yong Wang
