Dear Junwei,
I am sorry for the late response, but the error was very tricky to find. Fortunately the bug is very easy to fix.
Please open the file “src/dynamics/guoZhaoDynamics.hh” and change in lines 67 and 116 from “this->_momenta.computeRhoU(cell, rho, u);” to “this->computeRhoU(cell, rho, u);“, i.e. remove “_momenta.”.
Best regards,
Fabian
