hesham is on a distinguished road
i'm trying to simulate internal combustion engine using ANSYS 15 IC engine .
but when i run the solution in parallel mode floating point problem appears after few iterations and fluent window closed.
when i run the solution using serial mode the " invalid float" error appears after the first time step .
please, what can i do to solve this problem?
i searched this site and tried a lot of suggestions here but it didn't work.
what is the problem and how can i solve it?
please help me
thanks
