Hello,
i am analysing cfd analysis of pressurised gas leaving tank. For that to create geometry i used icem cfd. Meshing looks coreect and i modified it for erros too. but when i try to solve using ansys fluent..

fluid: ideal gas
turbulence model used: k-epsilon ,relaizable,scalable wall function
boundary condition:
axis-symmetric
wall: convection----287K-----45W/m2K----0.001mm thick
operating condition: press:101325, density:1.225,y-gravity:-9.81m/s2
tank inside condition:1013250,550K
tank outside condition: 101325,300K
------------------------------------------------------------------------
Divergence detected in AMG solver:k
divergence detected in AMG solver: epsilon
Error at host: floating point exception
Divergence detected in AMG solver
Error at node 0: floating point exception
--------------------------------------------------------------------------
there can be a problem in meshing too..because i am new in icem cfd.
here i am attaching its meshing file and geometry.
have a look at it and suggest edit in detail.
Thank you.
This is the last files i am sharing..i have created other geometries with inflation on all boundaries as well but the error was same in fluent.
