I'm working on a nozzle-simulation and have a problem which I couldn't solve it. I would be happy for your help.
I'm trying to plot along a created line with Fluent. I created this line with 2 points. If I try to plot I get an error: Cannot plot along curve length .... see screenshot. If i plot with direction vector it strangely works. But I need the plot with curve length.
One solution is to derive a equation for the curve length depents on the direction vector. But I want to take this solution at last.
Why I get the error: Cannot plot alonge curve length ...? I get this error for all variables on the Y axis which I tried to plot like volumefraction, velocitiy, ... Does anybody know it?
The white line is the divergent wall, the yellow line is the axis, the black line is the created line. The created line begins on the wall and ends on the axis.
