Fluent error: Fatal error (Segmentation fault)

shufang · August 25, 2014, 20:09

Hi Everyone,

I am running a multiphase simulation (i.e oxygen transfer from air to water). My model enables the species transport. I did not include any UDF, but I kept got error message :Fatal error (Segmentation fault).

If I disable the species transport, it will be okay (but it cannot be disabled because I need to specify oxygen as the transport species).

My current ansys version is 15.0.

Anyone has any idea how to solve this problem?

Thanks!!

it means that the solver is looking for something in the memory, but cannot find it. Did you enable species tracking and set all the species correctly? Also initialized them to some value?
