Class
    Foam::regionModels::vibrationShellModel
 
Description
    Intermediate class for vibration-shell finite-area models.
 
Usage
    Example of the boundary condition specification:
    \verbatim
    <patchName>
    {
        // Mandatory entries
        vibrationShellModel     <word>;
        p                       <word>;
 
        solid
        {
            // subdictionary entries
        }
 
        // Inherited entries
        ...
    }
    \endverbatim
 
    where the entries mean:
    \table
      Property   | Description                            | Type  | Reqd | Deflt
      vibrationShellModel | Name of vibration-shell model | word | yes | -
      p          | Name of primary pressure field         | word | yes | -
      solid      | Solid properties                       | dict | yes | -
      as         | Name of shell acceleration field    | word | no | as (suffix)
      ps         | Name of pressure (source) on shell  | word | no | ps (suffix)
      ws         | Name of shell displacement field    | word | no | ws (suffix)
    \endtable
 
    Naming changes from 2506 and earlier:
    \table
      Keyword  | Description               | Keyword (old) | Deflt (old)
      as       | Acceleration (shell)      | - | "as_" + regionName
      ps       | Pressure on shell         | - | "ps_" + regionName
      ws       | Displacement (shell)      | - | "ws_" + regionName
    \endtable
 
    The inherited entries are elaborated in:
