mesh sensitivity test
 
Hi guys,

The curve of mesh sensitivity test, i.e. a classical variable VS # of node, does it matter if the curve is increasing or decreasing to a constant value? As long as the slope become smaller and smaller, the trend can either increase or decrease, am I right? Thanks

Hi,

You can approach the asymptote from above or below, it does not matter.
