I’d like to have a scratch variable to keep track of some index values between time steps to speed up a table lookup. My first try was to use <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>SCRATCHCENTERVAR RIDX <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>In my Config file, and then try to read from/write to the scratch variable by referencing <o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>blkPointer(RIDX_SCRATCH_VAR,I,j,k)<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal> However, it seems like in Flash.par, RIDX_SCRATCH_CENTER_VAR has the same value as DENS_VAR, which leads to a rather unfortunate series of errors whenever I write to it and instead end up overwriting DENS_VAR. Does anyone have advice with how I should actually go about reading/writing the scratch vars?<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal>Thanks,<o:p></o:p></p><p class=MsoNormal>Varchas Gopalaswamy <o:p></o:p></p><p class=MsoNormal>PhD Candidate, Laboratory for Laser Energetics, <o:p></o:p></p><p class=MsoNormal>Department of Mechanical Engineering<o:p></o:p></p><p class=MsoNormal>University of Rochester<o:p></o:p></p><p class=MsoNormal><o:p> </o:p></p></div></body></html>
