AN IMPROVEMENT OF DYNAMIC MESH LIBRARY IN OPENFOAM FOR SIMULTANEOUS REFINEMENT AND MORPHING OF CELLS
M.J. Kang, S.B. Lee · Journal of computational fluids engineering · 2022
The native library of dynamic mesh in OpenFOAM was not reliable in simultaneous usage of cell refinement and morphing. The present study analyzed a treatment of the unsteady term for momentum conservation in the dynamic mesh library of OpenFOAM and proposed a new remedy to simultaneously use the cell refinement and mesh morphing. To ascertain the improvement of the new dynamic mesh library, we have applied it to the two dimensional simulation of a lid-driven open cavity flow by modifying an internal cell deliberately and compared the velocity profile with the previous data.
