Flow past a cylinder tutorial simulation

Please login with a confirmed email address before reporting spam

Hi, I've been having trouble generating the plots shown in figure 1,2, and 3 for the "Flow past a cylinder" simulation tutorial. I have version 5.2 of COMSOL Multiphysics.

I have followed all the instructions for generating the plots in figure 1,2, and 3 but I have gotten the following errors.

For the figure 1 plot (particle tracing with mass), I got the error:

"Evaluation of particle tracing data failed.
- Plot: ptr1 (Particle tracing with mass)"

For the figure 2 plot (1D plot graph), I got the error:

"Evaluation of result expression failed.
The argument to the reacf operator must be a dof name.
- Plot: ptgr1 (Point graph)"

And for the figure 3 plot (1D plot graph), I just got a straight line at zero.

I've retried following the instructions twice and still got the same errors.
