Summary0001279: ACMI method calculates wrong cell volumes and explicit gradients.
DescriptionAfter having problems with a particular case with solver pimpleDyMFoam, i looked for the problem origin finding that the ACMI boundary cells have an incorrect momentum predictor source due to erroneous fvc::grad(p) calculation.

I studied the problem using a simplified case by computing a basic operation: calculate the explicit gradient of an uniform scalar field on a domain composed by two regions, which are coupled with the ACMI strategy.

In the attached files there is a test case named "TestCase" , an user application in order to run the test case named "fvcGradFoam" and a pdf file with a more detailed explanation of the problem.
Steps To Reproduce1- Run Allrun.pre script
2- Run fvcGradFoam application
3- View fvcGradP and fvcInterpolateP fields in /0 folder.
4- View mesh cell volumes in terminal output when running the application.
TagsNo tags attached.
