Hi
Im making a FEM analysis on a simple bicycledesign. I have constructed it with protrusions, and i would like to make an optimization design study, so i can change, only the inner diameter of the bicycle skeleton.
I get a fatal error every time saying:
Initial Design Status
Parameters:
DFNstang&nbs p;&nbs p;3
DFstang  ;  ;17
DOstang  ;  ; 7
Goal: 3.6417e-03
Status of Optimization Limits:
1. max_stress_vm7.2223e+01 < 1.6500e+02 (satisfied within tolerance)
2. max_disp_mag5.0418e-01 < 1.0000e+00 (satisfied within tolerance)
Resource Check& nbsp;& nbsp;& nbsp;(15:55:56)
Elapsed Time(sec):&n bsp;416.07
CPU Time (sec):244.11
Memory Usage(kb):&n bsp;513815
Wrk Dir Dsk Usage (kb):& nbsp;1
Begin Optimization Iteration 1  ;(15:5 5:56)
Singular mapping, solid element: 2045822
The design study terminated abnormally.
The element with DBID 2045822 has invalid geometry. To correct
the problem, you may wish to provide seed points for AutoGEM
or change AutoGEM settings, and then remesh.
I really dont know what is wrong??
