Hi,

I am currently using star CCM+ to model Hypersonic Flow. I used for the inviscid case and it was alright although few problems were encoutered regarding the stability of the solver which needed fine tunning of the courant number.

However, when I added viscoucity to the model the (and chose turbulent flow in my physics model). I get a floating point exception error straight away (after 2-4 iterations)?

Does any one know whether Star CCM+ can solve viscous (turbulent) Hypersonic flow? If it can do then how can I get rid of the floating point error?

Also, Do you know If the stability of the solver is an inherent problem with Star CCM+ hypersonic solver (ASUM+ FVS)?

Thanks
