We solve for the decision, not for the mesh.

Verified FEM, CFD and NVH analysis for teams who need a defensible answer — traceable to the governing equations and to the standard it must pass.

Engineering calculators that show their working

Formula, your numbers substituted, assumptions and the reference — free tools, and Pro tools such as tube mill roll design from the flower pattern to the drawings.

Our own finite element solver

From a STEP file to a number you can defend: meshing, contact, linear static, modal, buckling and thermal. Here, a tube mill roll and its shaft under the forming load.

02 / VERIFICATION & VALIDATION

Every result is defended before it is delivered.

A colourful contour plot proves nothing. Each deliverable passes four checks, and the evidence ships in the report.

V1
Mesh independenceThe result is shown to stop moving as the mesh is refined.
V2
Boundary conditions justifiedEvery constraint and load is traced back to a physical source.
V3
Solver convergenceResiduals and energy balances are reported, not hidden.
V4
Checked against the codeThe margin against the governing standard is stated explicitly.

03 / PROCESS

Filter first. Then compute.

Inputs that do not change the engineering decision are removed before a single element is meshed.

  1. 01

    Filter the inputs

    We start from the decision you need to make, and keep only the loads, geometry and material data that actually change it.

  2. 02

    Model and verify

    Mesh independence and sanity checks come before any result is shown. If the model cannot be verified, it is not used.

  3. 03

    Validate against the standard

    Every result is checked against the code or standard the part must pass, with the margin stated.

  4. 04

    Report the decision

    You get the answer, the assumptions behind it and the traceable path from equation to conclusion.

07 / INDUSTRIES

Load cases we know by heart.

07 / WHY BADGERMECX

Why teams bring the hard ones to us.

01

We filter the inputs

Most analysis time is lost on data that does not change the answer. We decide what matters before we build the model.

02

Verification is not optional

Mesh independence, residuals and sanity checks are part of every job, not an extra.

03

Traceable to the standard

Each result is tied to the code it must satisfy, so your reviewer can follow the same path.

04

Engineers, not a render farm

You talk to the person who ran the analysis and can defend it.

05 / STANDARDS

Standards we work to.

Keep only the standards you actually work to — remove the rest.

09 / PROBLEM STATEMENT

Define the decision. We'll define the model.

Send the load case, the geometry format and the standard it must pass. You'll get a scoped, fixed deliverable back.
