[Archive] ArrayIndexOutOfBoundException

Message by abul anuar:
Hi all,
i keep getting this error every time i try to start a simulation. It started after######Mapping of Data on External BD######
at File “C:\SPIS_4_0_00_Windows\SpisUI\Bin\JyTop4.py”, line 377, in BuildSim
self.simu = NumTopFromUI(self.volMesh,
java.lang.ArrayIndexOutOfBoundsException:java.lang.ArrayIndexOutOfBoundsException: 0
All i know is the exception is thrown when the program tries to access the array using illegal index. i guess this has something to do with my mesh, which i couldn’t spot where. Everything is fine until i started the simulation. I check my mesh (and group assignment) and everything is fine (i guess).
At the moment, i haven’t change anything in the Global Parameter settings, everything is default setting. Could this be the reason why? Anyone has a suggestion on how to avoid this problem in the future?
Please help…thanks

I think i know the problem. it is caused by a ruled surface with a hole, which i successfully created and meshed, but produced simulation error. It works when i removed everything related to the formation of the hole panel.
The question now is, how do you make a ruled surface with an inner hole. Do you defined the points ( which may not lies on the ruled surface), or ermmm…?
