************************* **Moving Mesh Residuals** ************************* :: Moving Mesh Residuals = {yes | no} ----------------------- **Description / Usage** ----------------------- These nodal variables are constructed from the corresponding weighted residual functions of the solid momentum equations (activated with the *EQ = mesh** cards). The weighted residuals are formed using a Galerkin finite-element formulation. In the output EXODUS II file they appear as nodal variables **RDX**, **RDY**, and **RDZ**, corresponding to each of the independent components of the solid momentum balance (both pseudo and real). The permissible values for this postprocessing option are: ======== =============================================== **yes** Include the moving mesh residuals as nodal variables in the ouput EXODUS II file. **no** Do not include moving mesh residuals. ======== =============================================== ------------ **Examples** ------------ Following is a sample card which does not activate writing of mesh residuals: :: Moving Mesh Residuals = no ------------------------- **Technical Discussion** ------------------------- This option can be used to help understand convergence behavior of a particular problem, as it allows the user to visualize the pattern of residuals over the computational domain during a Newton iteration process. The intermediate solutions of a Newton iteration process can be activated with the *Write Intermediate Results* card. Contouring these residuals can indicate where the convergence of a problem is being delayed, and give the user/developer some clues as to the boundary condition or local region of the mesh which is responsible.
