To my surprise, the output happens every *two* timesteps. When I switch the parameter to 2, the same thing happens. So I get the following behaviour:</div><div><br></div><div>parameter value => actual output frequency</div><div>-------------------------------------------------------------</div><div>1 => 2</div><div>2 => 2</div><div>4 => 4</div><div>8 => 8</div><div><br></div><div>The grid has multiple refinement levels. I tried a smaller testsuite (perhaps one of the ML_BSSN tests, which are unigrid), and there "output_1Devery = 1" really did produce output every timestep.</div><div><br></div><div>I know a proper report needs a sample parameter file for reproducibility, but before I get that (not logged into the right machine right now), perhaps someone could tell me why this -might- happen? The logic in the IOBasic thorn seems simple enough ...</div><div><br></div><div>Thanks, Bernard</div><div><br></div><div><div><div><div>----------------------------------------------------------------------------- </div><div>Bernard Kelly -- CRESST Research Associate, NASA/GSFC</div><div> </div><div>Phone: +1 (301) 286-7243</div><div>E-Mail: bernard.j.kelly@nasa.gov</div><div>Web: http://science.gsfc.nasa.gov/sed/index.cfm?fuseAction=people.jumpBio&iphonebookid=13052</div><div>-----------------------------------------------------------------------------</div></div><div><br></div></div></div></div></div></body></html>
