About the software

A customized solver to solve the heat equation is using the OpenFOAM kernel. The main features of the solver are definition of spatially and time dependent heat fluxes which serve as boundary condition to the thermal model. Definition of temperature dependent material properties enables users to properly assess temperature change over time. Solver provides stability for rapid heat flux change in materials with low diffusivity coefficient, which is a known numerical problem.


Software details

The input to the customized solver is the same as standard input to OpenFOAM. Material properties and boundary conditions are specified in dedicated folders. OpenFOAM as stand-alone is a collection of approximately 250 applications built upon a collection of over 100 software libraries (modules). Each application performs a specific task within a CFD workflow. The snappyHexMesh application, for example, is a mesh generator for complex geometry, which can generate a mesh around a vehicle. The simpleFoam application could then simulate steady-state, turbulent, incompressible flow around the vehicle. Alternatively, the pimpleFoam application could run a transient simulation. The OpenFOAM User Guide describes these applications and how to execute them, either on a single processor or in parallel on multiple processors.
