Chapter 7:The General Postprocessor (POST1) Constant data are those that cannot be meaningfully combined, such as element volumes and element centroidal coordinates (see Table 7.4: Examples of Constant POST1 Results (p. 180)). These data are held constant (unchanged) when the program performs a database operation.

7.4.4. Mapping Results onto a Different Mesh or to a Cut Boundary Just as the PDEF command (Main Menu> General Postproc> Path Operations> Map onto Path) maps results onto an arbitrary path in the model, POST1 also has the ability to map results on to an entirely new mesh or to a portion of a new mesh. This functionality is mainly used in submodeling, where you initially analyze a coarse mesh, build a finely meshed submodel of a region of interest, and map results data from the coarse model to the fine submodel. POST1 offers two options for mapping results to a different mesh: Command(s): CBDOF GUI: Main Menu> General Postproc> Submodeling> Interpolate DOF Command(s): BFINT GUI: Main Menu> General Postproc> Submodeling> Interp Body Forc The CBDOF command maps degree-of-freedom results from the coarse model to the cut boundaries of the submodel. BFINT maps body force loads (mainly temperatures for a structural analysis) from the coarse model to the submodel. Both commands require a file of nodes to which results are to be mapped, and both commands write a file of appropriate load commands. Details about the submodeling technique are presented in the Advanced <strong>Analysis</strong> Techniques <strong>Guide</strong>. 7.4.5. Creating or Modifying Results Data in the Database You can do postprocessing without ever producing an ANSYS results file. All you need to do is create an ANSYS database containing nodes, elements, and property data, and then put your own results into the database using the following commands: Command(s): DESOL GUI: Main Menu> General Postproc> Define/Modify> Elem Results Command(s): DETAB GUI: Main Menu> General Postproc> Define/Modify> ElemTabl Data Command(s): DNSOL GUI: Main Menu> General Postproc> Define/Modify> Nodal Results Once the data are defined, you can use almost any postprocessing function: graphics displays, tabular listings, path operations, etc. Note 7.4.5. Creating or Modifying Results Data in the Database Issuing the DNSOL command requires that you have placed the data type (stress/strain) in the element nodal records. To get around this requirement, use the DESOL command to add a "dummy" element stress/strain record. ANSYS performs all load case combinations in the solution coordinate system, and the data resulting from load case combinations are stored in the solution coordinate system. The resultant data are then transformed to the active results coordinate system when listed or displayed. Therefore, unless RSYS,SOLU is set (no Release 13.0 - © SAS IP, Inc.
