Error Message!!

Matthew Roberts

I have recieved an error message, when i try to plot any contours of the default interior,that says

Error: FLUENT received a fatal signal (SEGMENTATION VIOLATION). Error Object: ()

Error message from graphics function Close_Segment: Nothing open - can't Close a 'segment'

Error message from graphics function Show_Selection_Source: Can't 'Show' - the 'locater' has been deleted

Can someone please tell me what this means, is there something wrong with my mesh??
