Detail Analysis System

1 of 8

New Feature

(1) Addition of Embedded Interface Element

An embedded line interface element is auto-generated from the line element embedded in a solid.

Embedded point interface elements are auto-generated at each end of the embedded line interface element.

Upgrade Contents

It is not necessary for a solid to share the nodes with a line element in the modeling stage as the nodes are automatically

generated at the embedded line interface element during the generation of the embedded interface element.

New Feature

(2) Addition of Strain-Life Approach (E-N Method) for Fatigue Analysis

Strain-Life Approach (E-N Method) estimates the fatigue from strain.Upgrade Contents

In case when an elastic body includes a plastic region, E-N Method is more accurate than Stress-Life

Approach (S-N Method).
