# Find out it works — before the tool's cut and the metal's poured.

*Material removal · casting fill & solidification · AM distortion · confidence*

Partimation runs the physics behind every process before you commit real material to it: verified material-removal simulation on the machining side, GPU fill-and-solidification simulation on the casting side, and a distortion trend check before a metal print goes to the build plate. Every result comes back with a confidence basis, not a bare number — so you know how much to trust it before you act on it.

- **GPU-accelerated** — fill and solidification solved on the voxel grid, not a lookup table
- **Verified, not assumed** — machining plans checked against real material-removal simulation
- **Confidence, always** — every result names its basis — prior, calibrated, or a review flag
- **Cross-process** — one physics layer behind machining, casting, and metal AM

## The expensive way to find out something doesn't work is to try it for real.

- **The scrap shows up on the machine, not the screen** — A toolpath leaves stock the tool can't reach, or gouges where it can — and you find out only after real material is already clamped to the table and the cycle's already run.
- **The mold doesn't warn you before the pour** — A cold shut, trapped air, or a riser that freezes before the casting it's supposed to feed — discovered after the tool's already cut and the metal's already poured. That's scrap, rework, and a delayed ship date.
- **Every process gets picked on gut feel, then paid for being wrong** — Mill it, cast it, print it — the choice gets made before anyone runs the physics, because running it separately for each process is its own specialist's job that most shops can't justify.

## The physics behind every process, checked before you commit to it.

- **Verified before the spindle turns — Machining plans checked against real material removal** — A voxel material-removal simulation runs the toolpath against the part's real stock model — reconciled cycle time, unreachable features flagged, leftover and gouge depth called out — before a single real cut happens.
- **The pour, simulated, not eyeballed — GPU fill and solidification physics on every casting** — A free-surface fill simulation predicts fill order, last-filled regions, and trapped-air risk; a transient solidification solver predicts solidification order and confirms risers actually freeze after the regions they're meant to feed. Live today inside Castimation.
- **Know the curl before it crashes the build — Metal-AM distortion trend and support-minimizing orientation** — A thermal-distortion trend check flags the shelves and overhangs most likely to curl into the recoater blade, and a support-volume scan ranks build orientations by how much support material each one costs you.
- **Every number names its basis — Confidence you can act on, not just a result** — Every result carries a confidence value and a named basis — a published prior, a calibration built from your own shop's actuals, a deterministic rule, or a flag that it needs human review — and every solver is checked against analytic theory before it ships, not just tuned to look right.

## Four steps from a model to a result you can act on.

1. **Drop the part** — Upload a model; Partimation picks the physics that applies — removal, fill, solidification, or distortion.
2. **Run the simulation** — GPU-accelerated where it counts, on the same voxel grid the rest of the analysis already uses — not a rule-of-thumb estimate.
3. **See the risk, and the confidence** — Every flag names the rule or model behind it, and whether it's a published prior or calibrated on results you've actually seen.
4. **Compare before you commit** — Weigh build orientations, rigging options, or a toolpath revision against each other before you cut a tool or pour a mold.

## In the cloud by default. Behind your firewall when it has to be.

- **Cloud — Nothing to install** — Sign in and run a simulation from any browser. We run the GPU compute, ship the updates, and keep your data yours — the shared model only ever learns from your own results to calibrate your confidence.
- **On-prem & air-gapped — For parts that can't leave the building** — Aerospace and anyone under NDA can run the whole thing on their own hardware. Licenses and updates are signed files — it never phones home, so an air-gapped install stays air-gapped.

## Casting simulation has a deeper home. Go there for the full depth.

Castimation is where fill and solidification simulation lives end to end — rigging, gates and risers, pattern and core tooling, casting yield, and cast-then-machine routing, all built on the same GPU physics described above. Same account, same cost model, tuned for the foundry.

**SimDFM → Castimation — The pour, simulated end to end** — Everything on this page, plus the casting specifics:

- Fill simulation (GPU)
- Solidification order
- Rigging + risers
- Casting yield
- Cast-then-machine

## Simulation runs across every process in the Partimation suite.

One physics layer, called by machining, additive, and casting alike — see the rest of the suite at [partimation.com/#modules](https://partimation.com/#modules).

## Frequently asked questions

#### Which parts of this are real simulation and which are advisory checks?

Two of the three are real solvers: voxel material-removal simulation on the machining side, and GPU fill plus transient solidification physics on the casting side. Fill returns fill order, last-filled regions, and trapped-air risk; solidification returns freeze order and whether the risers feed the regions they are meant to. The metal-AM distortion check is a trend indicator, not a build simulation, and is labelled as one.

#### Does the CNC simulation check for crashes with the fixture or the machine?

The removal simulation reconciles cycle time against the real stock model, flags features your tooling cannot reach, and calls out leftover stock and gouge depth. Collision, fixture, and machine-envelope modeling are not part of that run and are not claimed for it. Verify the crash question in your CAM or on a dry cycle; what comes back here is what the cutter removes and what it misses.

#### What does the metal-AM distortion check actually predict?

The distortion check flags the shelves and overhangs most likely to curl into the recoater blade on a metal SLM build. Read it as a ranking of risky features rather than a build simulation: no residual-stress field comes back, and no compensated geometry comes back either. Use it to decide what to redesign or support beforehand, then prove the build itself on the machine.

#### Do I need special hardware, and how are simulation runs charged?

Simulation runs on our GPUs in the browser — there is nothing to install and no workstation to buy. Pro includes 30 runs a month, Shop pools 150 across its 5 seats, and an On-prem license runs unmetered on your own hardware. Metering counts compute runs only: DFM findings and should-costing stay unmetered, so screening a part never spends a run.
