what is your exact workflow?
does this happen on a simple pipeflow problem or only on your model?
what version of office are you using?
personally I have always attached sceenshots into the reports manually to have more control of how they go in..etc.
nothing out of the norm really, after FlowSimulation finished its calculations, i just go onto produce an Automated generated report.
Click on "From Template" and then move on to trying to attach images like Cut Plots from Solidworks.
Im basically running simulation on some valves, nothing complicated no pipe works involved.
Currently running Solidworks 2015 and MS Words 2010.
I guess Manual Image Input would be the way to go.
there is a pretty big gap between 2015 solidworks and word 2010 that might be part of the issue, i don't have that combination to check
have you spoken to your reseller?
You can always click New Document to generate a report that can have picture attachments manually.
