How Nodes are Generated on Shafts in RomaxDT?

(This Q&A has been posted by Cadence Technical Support for the benefit of our community members)

    When components such as bearings are placed, nodes are created accordingly. However, additional nodes are automatically generated along the shaft. Node generation along a shaft is governed by the Timoshenko beam theory, which requires dividing long shaft sections for accurate static analysis. The 'Max length to diameter ratio for parallel section' setting (under Analysis settings) controls how many nodes are created. Lowering this ratio increases node count, while raising it decreases nodes. Disabling this setting stops extra node generation, but keeping it enabled is recommended for accuracy.
