Hi all, Can somebody tell me if the ADRsolver can handle: 1. AdvectionVelocity from a set of files i.e. TIMEDEPENDENT: <FUNCTION NAME="AdvectionVelocity"> <!--F VAR="Vx,Vy,Vz" FILE="geom_saturated.fld:u,v,w" /--> <F VAR="Vx,Vy,Vz" TIMEDEPENDENT="1" FILE="geom_%03i.chk:u,v,w" /> <!--E VAR="Vy" VALUE="0" /> <F VAR="Vz" FILE="geom_2D.bse:w" /--> </FUNCTION> It seems as if it just uses the first file (or I am doing sth. wrong). I looked into the UnsteadyAdvection.cpp and AdvectionVelocity seems to be evaluated only at initialization. Is it the case? 2. Have Forcing f from a file: <FUNCTION NAME="Forcing"> <F VAR="Q" FILE="geom_240.chk:Q" /> </FUNCTION> For the above I am getting: Fatal : Level 0 assertion violation Function is defined by a file.
