OPTUM CS allows engineers to simulate step-by-step construction sequences, including:

• Excavation stages

• Backfilling

• Dewatering

• Structural installation

• Soil reinforcement

This makes it ideal for analyzing real project workflows where stresses evolve over time.

---

3. Wide Range of Soil and Material Models

The software includes multiple constitutive models, such as:

• Mohr–Coulomb

• Modified Cam–Clay

• Linear elastic

• Undrained shear models

• User-defined material behavior

This ensures compatibility with various geotechnical conditions—from stiff clays and granular soils to soft organic layers.
