Dear Foamers,

I am new to OpenFOAM i need your help to avoid the following error.

Its a case on valve simulation using interFOAM.

I followed the waterchannel tutorial as it resembles my case.

When I run the case I am getting the following error.

Please help me.

Hello Sam,

The answer for your question lies in the error message. Remember, OpenFOAM is case-sensitive. Even though I don't have access to any of your files in the 0/ or constant/ directories, I believe if you set your flux source to "INLET" instead of "inlet' the error should be fixed. The valid patch names are listed in error message and you can see that all of the available options are in upper-case letters.

Hope that helps!!

Hi Vabishek,

I have solved it. Actually in controldict there were some functions written to calculate the massflux. So I removed them.

thank you.
