Hello, as a newbie i have several issues due to moving grid: 1) i have a very simple TRANSIENT case: 2) mesh is a cube and its vertices to be accelerated in NEWXYZ in x direction only CODE IN NEWXYZ

integer I J

real cons1 slope Vo Vx

cons=0.1

Vo=0.1

slope=cons1*Vo

Vx = Vo + slope*ITER CC---- accelarate in x direction

DO 10 I=1,NDMAXU

VCORN(1,I)=VCORN(1,I) + 0.1*TIME 10 CONTINUE

RETURN

END 3) through inlet a constant velocity, outlet default i have NOT attached (is this needed for my issue?) 3) i do not want to use EVENT module for starters 4) i give timestep command 4) i give per command PREVIEW and MOVING GRID: rcons 4 1 mvgrid on no event 5) i then save star.mdl, geom and prob files 6) in another window starlink, user subroutine yes, star

7)at post processing: iter 1 for vertices shows with VLIST ALL and iter 10 shows same values for vertex coordinates

getc all shows different values for velocity though. PLEASE HELP asap Greetings
