[Getdp] some warning message

[Lin Ji]

Dear Christophe,
     I got the following warning message when I postprocess the solution
to the elastic wave equation to generate the timetable data. Can you tell
me what it means? Solving the elastic wave equation seems to be fine. It
converges at each time step. Thanks
