|message_desc=Using the Quadtree Control File (QCF) command <tt><font color="blue"><tt>QUADTREEQuadtree MESHMesh PROCESSINGProcessing METHOD </tt>Method</font> <font color="red"><tt> == </tt></font> <tt>MEMORYMemory EFFICIENTEfficient</tt> can significanlysignificantly increase mesh processing time and is not recommended when using more than 10 nesting polygons. The '<tt>Memory Efficient</tt>' option treats each GIS polygon in the 2d_qnl layer as a separate domain for the processing of geometry inputs. Whilst being more memory efficient during mesh creation, this may be slower to initialise. It has no effect on the speed of the hydraulic computations or the memory demand during the hydraulic calculations.
|suggestions=Update the QCF command to the default method '<tt>FAST</tt>', <tt><font color="blue">Quadtree Mesh Processing Method</font><font color="red"> ==</font> FAST</tt>. Refer to the <u>[https://docs.tuflow.com/classic-hpc/manual/latest/ TUFLOW Manual]</u> for more information on quadtree mesh processing.
|suggestions=Please contact [mailto:support@tuflow.com support@tuflow.com].
