i m using 8gb ram, i7 processor
i m doing problem of cfd of a steam turbine blade in ansys cfx
i m getting the following error:

please help as it is my thesis work and i have to submit it soon
is it somethinf to do with geometry or mesh, or boundary conditionf
i have used serial solver with 3 partitions

[ashwani.thakur]

also the same problem is working fine when i m using a box domain instead of a curved domain for blade
can there be a problem in inlet flow direction of steam defined by me

There is some sort of problem with the interpolation of an initial condition onto your simulation. You have not provided any details of what you are doing so I cannot say anything more than that. I do strongly recommend you have a look at the tutorial examples. A few of them use initial condition interpolation I think. That is the best place to sort out basic problems like this.

i m doing the problem on steam flow across a rotor blade

i reduced the no. of nodes and elements and the problem worked fine but it showing following message during solving:

****** Notice ****** |
| A wall has been placed at portion(s) of an INLET |
| boundary condition (at 1.6% of the faces, 1.5% of the area) |
| to prevent fluid from flowing out of the domain. |
| The boundary condition name is: inlet. |
| The fluid name is: Fluid 1. |
| If this situation persists, consider switching |
| to an Opening type boundary condition instead. |
+--------------------------------------------------------------------+
+--------------------------------------------------------------------+
| ****** Notice ****** |
| A wall has been placed at portion(s) of an OUTLET |
| boundary condition (at 10.7% of the faces, 11.1% of the area) |
| to prevent fluid from flowing into the domain. |
| The boundary condition name is: outlet. |
| The fluid name is: Fluid 1. |
| If this situation persists, consider switching |
| to an Opening type boundary condition instead.

what does it mean and can it affect my results to use opening instead of inlet and outlet conditions.
