Hi,
I am trying to compute a flow wherein the mach number, angle of attack, freestream pressure, freestream temperature and reynolds number are a function of time. I have a quadratic function for the variation and I am aware that this can be achieved by getting the value of the current iteration using config->GetExtIter(). However I do not understand where exactly to change these values (which subroutine/class and line number) as there could be multiple places. I am using the following boundary conditions: Farfield and no-slip wall. Flow: NS equations without turbulence modeling, without mesh movement. Numerical scheme HLLC (possibly with preconditioner) I am also having difficulty understanding how the function GetCharacPrimVar(val_marker, iVertex) works. Kindly help me with the above problems. Thanks. |
