Hi everyone, I am new to precice , and I what to use the precice to do FSI. My coupling situation is flow pass by naca0012 using rhoPimpleFoam for fluid ,and solid using calculix.
Here is the error from rhopimplefoam:
--> FOAM FATAL ERROR: (openfoam-2212 patch=230612)
Different dimensions for '(a = b)'
dimensions : [1 -1 -2 0 0 0 0] != [0 2 -2 0 0 0 0]
the unit of [1 -1 -2 0 0 0 0] is the real pressure, and [0 2 -2 0 0 0 0] is the Kinematic pressure.
according to the FSI tutorial, in the incompressible fluid, openfoam using Kinematic pressure, but in the compressible fluid, openfoam using real pressure. so it may be the cause of the error. My question are how to fix this error when coupling compressible fluid with solid. What are the different of precice-adapter calculate the force and stress for compressible fluid and incompressible fluid.
Could anyone help me?
Best
