sure that your configuration is correct and that the multiplier against the
bore configuration results in the number of bores you have in the field. Depth,
conductivity, etc. also play a key role, but this is usually the reason I come
across.<o:p></o:p></span></p>

want to split the simulated field in two and have two GSHX fields to “draw”
from.<o:p></o:p></span></p>
