This slide is about multiphaseEulerFoam which is a CFD solver of OpenFOAM and can analyze multiphase flows. The theory and differences with multiphaseInterFoam are explained.
This document summarizes the steps to perform conjugate heat transfer (CHT) coupling between OpenFOAM and CalculiX using preCICE. The example problem models heat transfer in a heat exchanger with an inner fluid, outer fluid and solid. OpenFOAM is used to simulate the inner and outer fluids while CalculiX simulates the solid. PrecICE is configured to exchange temperature and heat flux boundary condition data between the solvers at mesh interfaces. The workflow involves creating meshes in OpenFOAM and CalculiX, setting up coupling configuration files, and running the coupled simulation over multiple timesteps.
Setting and Usage of OpenFOAM multiphase solver (S-CLSVOF)takuyayamamoto1800
The S-CLSVOF solver in OpenFOAM uses a coupled volume of fluid (VOF) and level set method to simulate multiphase flows. It uses a level set function to track the interface and reinitialize it, improving on the standard VOF method. The solver has been implemented in OpenFOAM versions 2.0.x and higher but boundary conditions for the level set function have not been fully developed. The document provides information on setting up and running a dam break tutorial case using the S-CLSVOF solver by modifying an existing interFoam case.

This document discusses two methods for obtaining contour surface positions from OpenFOAM simulations: 1) Using the OpenFOAM sample utility which extracts contour data along surfaces defined in a sampleDict file, and 2) Using Paraview to visualize and export contour data to CSV files. The sample utility creates surface data folders containing sampled contour positions, while Paraview allows contour visualization and automated output of positions over multiple time steps.
Spatial Interpolation Schemes in OpenFOAMFumiya Nozaki
The document discusses spatial interpolation schemes in OpenFOAM. It begins by explaining how spatial derivative terms in the finite volume method (FVM) are discretized by integrating over cell volumes and surfaces. It then describes how values at face centers are obtained by interpolating from cell center values using algebraic relationships and weighting factors. Common interpolation schemes in OpenFOAM include upwind, linearUpwind, linear, and limitedLinear. The specification of interpolation schemes on a term-by-term basis is demonstrated. Code examples show how schemes such as upwind, linearUpwind and midPoint calculate interpolated face values and weighting factors differently.
The document discusses dynamic mesh functionality in OpenFOAM. It describes how OpenFOAM handles mesh motions and topology changes using the Dynamic Mesh functionality. Settings for Dynamic Mesh are specified in the dynamicMeshDict file located in the constant directory. Solvers that can handle mesh changes have names containing "DyM", standing for Dynamic Mesh. Examples include pimpleDyMFoam and interDyMFoam. Various types of dynamic meshes are described, including those handling only motion and those enabling topological changes.
