<TITLE>Runtime error when trying to test Sod or Sedov</TITLE>
</HEAD>
<BODY>
<FONT FACE="Calibri, Verdana, Helvetica, Arial"><SPAN STYLE='font-size:11pt'>Dear Flash Experts,<BR>
<BR>
I am trying to test newest FLASH (3.3) version on a “chaos_4_x86_64” linux machine. <BR>
<BR>
I separately tried to built/run Sod and Sedov problems and I got pretty much the same errors in both<BR>
cases. Setup and build (gmake) processes give me absolutely no trouble. However, I get “hdf5 I/O”-related runtime errors<BR>
after executing ‘mpirun –np 1 flash3’ command. <BR>
<BR>
The strange thing is that runtime error messages totally change if I modify “lrefine_max” (default was set to 6) value inside<BR>
flash.par file. Below I copied last parts of 2 different error printouts I get when running Sod problem.<BR>
First when lrefine_max = 6, and second when lrefine_max = 3.<BR>
<BR>
I also tested flash3 executable using valgrind which seemed to indicate some memory leak issues. <BR>
<BR>
I’d really appreciate any suggestion on this matter. <BR>
Cheers,<BR>
Irakli. <BR>
