I am new to FEA constraining and I can not seem to properly constrain my model.
I have a public project with a lot of confusing errors for all the sim runs I have tried for my static nonlinear simulation with Pressure following.
The object is basically a pressurized balloon.
I have made the geometry a 1/4 shape with two symmetry planes in the X and Y directions.
I have not made a Z symmetry plane because gravity in the Z direction will make the balloon unsymmetrical in the Z direction.
In ‘Run 3’ I simply used the following boundary conditions:
Symmetry Plane X (all faces on the X symmetry plane)
Symmetry Plane Y (all faces on the Y symmetry plane)
Pressure Follower INTERNAL (all internal faces selected)
Fixed support node (a single node at the very top of the balloon is selected)
Here is a shot of the node I selected:
On ‘Run 3’ I get this error:
But when I click on ‘View’, to see the error, I am unable to find any Event Log or Solver Log to find out why the sim run failed.
The only run where an error is actually visible is ‘Run 1’ where it points to constraining error, which is why all my other runs attempt to constrain it properly, but they have all failed without being able to see any error text.
Any help would be appreciated…
