Hello,
I have an inlet profile data obtained from my previous work in *.csv format. I have initialized it via the "Initialize profile data" setup, but I unable to use it for an Inlet BC for my current simulation.
Any ideas will be greatly appreciated.
Best Regards
Ehsan Bakhtiari , I once had the experience of translating results in csv format as a boundary condition for another calculation. I calculated using this method the axial turbo compressor. As far as I understand it is necessary to write the boundary conditions from equivalent domains.
To do this in my case I performed calculations for 1.5 compressor stages (See fig. 1. the domain includes the inlet guide vane, the first stage, and the second stage rotor blade). Then I performed the calculation of this model and recorded the flow parameters in a csv file from the surface at the entrance to the second rotor blade (see figure 2).
After that, a started calculating the second model. This model included a second stage and a third stage working blade.(This model included the same domain of the second stage working blade from which data from the first model was recorded).
Before loading the boundary condition profile, I thought it was right to extend it, since my model is axisymmetric.I did this tools using the Tools-->expand profile data option (in Pre Module).After that, I got a second CSV file of boundary conditions. It different from the first one in that the boundary conditions were extended in the circular direction
Next I initialized this second csv using Tools--->Initialize Profile data (see fig.3).At the inlet boundary condition you have to check "Use Profile data",choose profile of BC, check "Generate Values" and push button Generate Values.All this looks approximately as shown in fig. 4 and fig. 5.
That's all. Using this method, I calculated a multi-stage compressor. I even got results that were similar to the truth.
To get an correct excel file format or the variable it self:
CFX-Post -> File -> Export -> Export
Type BC Profile
To import in CFX-Pre:
Tools -> Initialize Profile Data (import the profile)
Check the box on User Function to visualization
On the Boundary Condition, Basic Settings, select Use Profile Data and generate Values
Check on Boundary Details if the variable are set correct
As Vladimir told, the exported Profile Data must cover the same boundary condition domain.
