MODSIM (Unified Modeling & Simulation) connects CAD and CAE in a single workflow so validation can happen earlier, rework is reduced, and design iterations become faster. Learn the concept, benefits, and practical steps to implement it with Haliatech.
What is MODSIM
MODSIM is an approach that unifies the design and simulation process into one workflow, so a design change doesn’t always mean restarting the CAE workflow from scratch.
In simple terms:
- CAD and CAE work in one continuous process
- Engineering data is enriched step by step
- When the design changes, updates can flow into the simulation model more consistently and efficiently
In short, simulation becomes part of the design process, not a separate activity that always starts over.
MODSIM vs Traditional CAD and CAE Process
Traditional (linear) process:
CAD completed → geometry transfer → prep/mesh → simulation setup → run → design changes → repeat
MODSIM (loop/cyclical) process:
Design and simulation run in an iterative cycle, so:
- Design iterations are faster
- Late-stage rework risk is reduced
- Engineers can focus more on technical decisions, not repetitive setup tasks
Benefits You’ll Typically Notice First
These are the benefits most commonly sought by engineering managers and lead engineers:
1. Faster design iterations
By reducing rework caused by design changes, teams can evaluate more design options in the same amount of time.
2. Earlier validation
Performance validation happens earlier, so critical issues are found before the design becomes “locked in.”
3. Consistency and standardization
Standardized workflows make results more consistent across engineers and easier to repeat for product variants.
4. Better cross-team collaboration
With a more connected process, CAD and CAE coordination is no longer just “sending files” it becomes part of a traceable engineering workflow.
When Should You Consider MODSIM
MODSIM is usually relevant if you have one or more of these conditions:
- Designs change frequently
- Products have many variants
- The CAD and CAE process involves many handovers across teams
- A lot of time is spent on geometry prep, remeshing, and re-setting connections/BCs
- You need faster iteration along with process control
How to Get Started
To avoid starting too big, begin with a measurable pilot:
- Map the top 3 biggest rework areas in the CAD and CAE workflow
- Choose 1 pilot use case that changes frequently
- Create workflow templates: mesh rules, connections/contacts, BC patterns, naming
- Test scenarios: when the design changes, what auto-updates and what must be reviewed
- Once stable, scale to other projects/products
