Getting started, documentation, troubleshooting and MCP setup. For anything else, email founder@lattiform.com with your Mac model, macOS version, app version and the steps that led to the problem.
Getting started.
Step 1
Choose your purchase route
Choose Student, Individual or Commercial on the website pricing page. Paddle displays the price, currency and tax before checkout. Website trials last seven days and require payment details.
Step 2
Get the app
Once Paddle confirms your purchase or trial, sign in to the Lattiform account with your checkout email to get the Mac app and your licence key.
Step 3
Install
Open the ZIP and move Lattiform.app to Applications. Lattiform requires Apple Silicon and macOS 14 or later. The 8 GB memory entry configuration is compatibility guidance, not a tested minimum for large engineering studies.
Step 4
Subscribe or add your key
In Lattiform, open Settings → Licence to add your key. Activation is optional in the currently published direct edition; your licence still determines the permitted use.
Step 5
Run a first study
Model or import a part in CAD, choose Continue to FEA Lab, set supports and loads, read Preflight, then solve.
A first linear static bracket study.
A worked STEP bracket example showing the CAD-to-FEA Lab workflow. Captures are from a development build, not a numerical benchmark or an exact walkthrough of every control in the current release.
1. Import a bracket and check its dimensions
Use a STEP mounting bracket you have permission to analyse. Import it into Model Prep and compare a known dimension with your drawing; confirm the units, body count, holes and fillets before continuing. Save the document. A successful import alone does not establish that the geometry or units are correct.
2. Continue to a linear static study
Use Continue to FEA Lab to carry the part, its material and face names into a study. Choose linear static and inspect the Analysis Body view: the solver uses a regular grid of cube elements, not the exact CAD boundary. This guide does not use modal or buckling analysis, which refuse partially filled grid cells.
3. Define material, supports and a distributed load
To mirror the website’s illustrative development scenario, use aluminium 6061-T6, fix the underside and distribute a total 500 N load in negative X over the outer upright face. Check the axes and selected area, and confirm that 500 N is the total load rather than a pressure. These are example assumptions, not validated design loads for your bracket.
4. Check the mesh and solve readiness
Choose an element size that resolves the bracket’s thickness, holes and fillets within your Mac’s memory. The development example used a 1 mm grid; that size is not a recommended minimum for other parts. Resolve the app’s geometry, material, support, load and memory warnings before solving. Recheck supports and loads after any CAD edit.
5. Review the solve before interpreting stress
Read the reported convergence state and warnings before relying on a contour. Check the stress and displacement units, deformed-view scale, load directions and reactions. Compare the applied load with the support reactions, and check the deflection direction against a simple hand calculation where possible. A completed solve does not certify the design.
6. Repeat with a finer mesh and record the change
Keep the same geometry, material, supports and loads, then repeat with smaller elements if memory permits. Compare displacement and stress at consistent locations, away from point loads and sharp corners. Solver convergence and mesh convergence are different checks; singular stresses may not settle with refinement. This setup guide supplies expected checks, not a pass/fail benchmark or a predicted stress value.

Troubleshooting.
Settings → Licence refuses my Individual key
Yearly Individual keys work in the current version. If an earlier version refuses yours, choose Lattiform → Check for Updates; until then the app still runs, because activation is optional.
A study will not start
Open Preflight. It names anything missing or wrong, such as a material, a support or a load, before a solve can start.
Modal or buckling refuses my part
Both need whole grid cells, so a part whose surface leaves cells partly filled is refused. That includes most imported and CAD parts.
An import is refused
Files over 64 MiB, or content the app cannot read correctly, are refused and the study is left unchanged. Send us the file if you think it should work.
The study needs too much memory
A linear static study that would need more than half of your Mac’s memory is refused before it starts. Use a larger element size or refine only the region you need.
Checking for updates
For the directly downloaded Mac app, choose Check for Updates or enable automatic update checks in Settings. Updates are signed and verified before installation.
MCP setup.
The directly distributed Mac app includes the local MCP helper at /Applications/Lattiform.app/Contents/Helpers/lattiform-mcp. Connect an AI client to that helper, then request get_capabilities to inspect its actual supported tools and schemas for your installed version.
