Problem with the results in abaqus

[lem0n23]

Hi, i'm new to abaqus and i am trying to make some tests in a wheel. The wheel is made only by carbon fiber.
I think that i made everything right, choosing the material, the composite layups for the rim and for the wheel walls, the load. However i'm not so sure about the BC's that i choose, they might not be the right ones.
So, when i run the job, in the result the deformation doesn't match with the expected...the expected is the rim to bend on the extremity's due to the applied pressure. But the result shows an expansion of the wall near to the rim as i show in the picture

I appreciate all the help

In the Visualization Module: Go to Options--->Common--->Deformation Scale Factor--->User Defined--->Value

everything solved. Tell me one last thing. I don't know exactly how to explain it but..how can i apply a force to a restricted area of the rim? for instance, i wanna apply a side force on 20º of the rim. How can i do that?

Set up a partition around the rim. It would be two cirlces concentric to your part. You'll find the partition feature in the assembly module. If you need further explanation let me know.

I've tried what you said but i was not sucessfull. I don't think though that i'm explained right. I need to make a "sector" in the rim to apply forces in the zone that the wheel touch the ground. In the partitions menu the options are more oriented to faces, so i can't do anything with my multiple faces 3D rim

I suppose if you still have the cad model, then you can modify it there. I believe when you import a model into abaqus it will have an element break corresponding to the lines in your cad model.

I managed to make the partition in abaqus...that is ok, but now i'm having trouble with the results caused by this load on the sector. I'm getting this error
Error in job Job-1: Too many attempts made for this increment

i have already increased the maximum number of increments, decreased the initial increment size and the minimum value.

I'm sure that the cause is this load with the sector, because when i try without that load there are no problems

Actualy i'm having the error when i apply a 2 force..not only on the sector but on every place where i place it.
