Hi Varchas,

<div class="">I suspect you might get the wrong pointer for the scratch variables (not the way of getting solnData). You could get the correct pointer for the scratch variables by calling</div>

Has anyone had experience with using scratch variables in FLASH? 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<span class="Apple-converted-space"> </span><o:p class=""></o:p></div>

In my Config file, and then try to read from/write to the scratch variable by referencing<span class="Apple-converted-space"> </span><o:p class=""></o:p></div>

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 class=""></o:p></div>
