Tolerance Report
Click Tools > Tolerance Report if you experience problems in meshing an assembly model in either native mode or FEM mode. If a significant difference exists between the tolerance values of assembly components, then the mesh generation may fail for the assembly. To mesh the assembly successfully, the tolerance values associated with each assembly component must be close to each other.
Tolerance, as reported by Creo Simulate, is calculated in a manner similar to absolute accuracy. However, the calculated values are different. Click Tools > Tolerance Report to compare the tolerance—and, in effect, the accuracy—of assembly components if the meshing of your assembly fails.
The tolerance report provides:
Details about all the components that have geometry. The report includes information about each component name, the associated tolerance value, the accuracy type, and the accuracy value in a tabular format.
The tolerance and accuracy values for all the assembly components whose individual tolerance contributes to the global tolerance of the assembly.
* The global tolerance value of an assembly is calculated based on the individual assembly component tolerances. If the assembly contains entities such as quilts or beams, the report includes the tolerance value for the assembly itself. To better understand how to use the values in this report, you must have background information on model accuracy, both relative and absolute.
Listing of components based on their tolerance values with the component having the highest tolerance value listed first.
For Creo Simulate to successfully mesh the assembly, these tolerance values must be very close to each other. When meshing large assemblies, keep these guidelines in mind to overcome the meshing limitations.
