Hi,
I made an analysis of a train and put cilinders around the wheels for the rotating regions.
Then I create several goals but when i do the calculation some of the goals don't seem to
converge.
is there a reason for this? Is the computational Domain of a train too big?
thx
You might want to try the real wall option to give the wheel surfaces an angular speed as opposed to the rotating regions approach which it seems was used. This would be far simpler, more efficient and more elegant.
