Mesh convergence study
Deliverable: One component analysed at four mesh densities, with peak stress plotted against element count and a written statement of the density at which the result stabilised.
Course
Ansys (Finite Element Analysis)
Finite element analysis taught around validation, because a colourful stress plot is easy to produce and only useful once you can show it is not nonsense.

Projects you will build
Validated cantilever analysis
Deliverable: A structural analysis whose result is checked against a hand calculation, with the two compared and any difference explained rather than dismissed.
Assembly with contact
Deliverable: A bolted assembly analysed with realistic contact and pretension, including a written account of what was changed to make it converge.
Analysis report
Deliverable: A full report on one analysis stating geometry simplifications, material assumptions, boundary conditions, convergence evidence and the limitations of the conclusion.

Placement assistance
Every student gets placement assistance — that is what 100% placement assistance means. It is support for all, not a job for all. We do not promise a specific salary, a specific number of interviews, or placement at any named company, and you should be wary of anyone who does.
What is included
- A place in the monthly placement drive, held every third Saturday
- The readiness programme every second Saturday — mock interviews and preparation
- CV review against the specific roles you are targeting
- Portfolio review, so your project work is presented the way a reviewer will read it
- Access to the vacancy pool employers send directly to the Samyak network
- Guidance on which roles realistically fit your background and which do not
- A place in the next drive, with coaching, if you are not selected in this one
What is not included
- Any guarantee of a job, an interview, or a particular salary
- Placement at a named or partner company
- Applying to jobs on your behalf
- Support before you have completed the course and its project work
- Visa, relocation or overseas placement assistance
Anyone can make a colourful picture
FEA software will always give you an answer. It is under no obligation to give you a correct one.
Constrain a part in a way that does not match reality and the stress halves. Leave a sharp internal corner and it goes to infinity. Import geometry with a sliver face and the mesh degenerates. Every one of these produces a plot that looks entirely convincing.
So this course is organised around validation. The analysis is the easy half.
Hand calculation first, every time
Before you accept a number from the solver, you should already roughly know it.
A cantilever has a formula. A pressure vessel has a formula. If the software disagrees with the formula by a factor of forty, the problem is your boundary conditions, and no amount of mesh refinement will tell you that.
The second project is graded on the comparison rather than the analysis, and students are frequently surprised by which of the two was wrong.
Convergence is not optional
A result from a single mesh is not a result.
Peak stress at four element densities, plotted, showing where the curve flattens — that is the evidence a reviewing engineer will ask for, and producing it takes an afternoon. Reporting a number without it is the most common thing that gets a junior analyst’s work sent back.
Know when the maths has no answer
Refine the mesh at a sharp internal corner and the stress rises forever.
This is a singularity, not a real stress, and beginners have reported enormous numbers from them in genuine design reviews. Recognising one, and knowing whether to add a fillet or to disregard the peak, is a basic competence this course makes sure you have.
Questions
Ansys (Finite Element Analysis) — frequently asked questions
Do I need to be good at mathematics for FEA?
You need strength of materials and mechanics — stress, strain, bending, and a feel for how a structure carries load. You do not need to derive the stiffness matrix. What matters far more is engineering judgement, because the software will always produce a colourful answer and only judgement tells you whether it means anything.
Why does the course insist on hand calculations?
Because it is the only independent check you have. If the software says 180 MPa and a beam formula says roughly 175, you can proceed. If the software says 4 MPa, something is wrong with your constraints and no amount of mesh refinement will reveal it. Analysts who skip this step ship confident nonsense.
What is a stress singularity?
A sharp internal corner in the geometry where the calculated stress rises without limit as you refine the mesh — it never converges, because the mathematical model has no real answer there. Beginners refine and refine and report an enormous number. Recognising a singularity and knowing to disregard or fix it is a basic professional competence.
Is this enough to get an FEA job?
It gives you the workflow, the validation discipline and a written report to show, which is what interviews probe. FEA hiring generally wants a solid mechanics background alongside, so it converts best for mechanical, civil and aerospace graduates. We will give you a straight read on your own position.
