Cannot Open .sim (Floating Point Exception)

trex930 · July 30, 2010, 05:18

Hi all!

Ran into a major problem today. I had finished running my simulation in StarCCM+ and everything was dandy so I saved it and exited the progam. After a couple of hours, I tried to re-open my .sim file and heres the error i get.

"A floating point exception has occurred: foating point exception [invalid operation]. The specific cause cannot be identified. Please refer to the toubleshooting section of the User's Guide."

the odd thing is, I had always thought floating point exception occurs if something was getting divided by a zero. But the simulation is finished. so that shouldnt happen. Anyone have any idea on how to fix this?

Thanks in Advance,
T

Hi trex,

such an error cannot only occur while obtaining a solution, but also if you use an fieldFunction and divide by zero within this function.
Do you use any fieldFunctions which could create such a behavior?

Does the same error occur if you open the backup (.sim~) file?
