I have recently run into this issue. I have been running some flow simulation analysis to find drag and lift forces. Everything was working fine when suddenly when I run my 3rd simulation this happens.
as you can see there is no time input on calculation time left. Also, i don't see the blue calculation bar on the bottom of the screen although the iterations are performed. When I look at the goals table the achived percentage stays at 0% even though I see the values for drag and lift forces being computed.
Will appreciate the help.
