you could check the following: UpS`KgF"v
m>6,{g)
- if the surface/element tilt is too large LdAfY0
b#^UP
- enough analysis rays used? kGMI
?
o84!$2P+w
- have you used Coherent Data option under Detector setting. T?c:z?j_9
DEL#MD!
Someone above was right about that the non-sequential mode only uses geometric rays but you could see inteference fringes using Coherent Data.
