ANSYS Mechanical
Industry-leading FEA platform for structural, thermal, and coupled-physics simulation across industrial engineering applications.
Official websiteAbout ANSYS Mechanical
ANSYS Mechanical is a premier finite element analysis (FEA) platform delivering comprehensive structural, thermal, and coupled-physics simulation capabilities. It enables engineers to predict how product designs will behave in real-world operating environments, covering static structural analysis, modal analysis, harmonic response, transient dynamics, and fatigue life prediction.
At Shirsh TechnoSolutions, ANSYS Mechanical forms the backbone of our structural simulation practice. We leverage its advanced nonlinear material models, contact algorithms, and adaptive meshing to solve complex industrial problems — from bolted joint assessment under cyclic loading to creep-fatigue interaction in high-temperature components.

Why Fixed-Tilt Ground-Mount Solar Structures Fail
Fixed-tilt ground-mount is the structure everyone treats as solved. No moving parts, a straight load path from module to rail to post to ground, a static wind check, done. That reputation for simplicity is precisely why these structures fail, not from exotic physics, but from foundations pulled out of the soil, connections detailed for the wrong load direction, slender members that buckled under uplift, and corners that saw far more wind than a borrowed coefficient ever admitted. Walk the load path with a failed array in front of you and the causes are rarely mysterious. Here is how to read the damage, and the analysis chain that would have caught it on paper.
ReadWhy Single-Axis Solar Trackers Need FEA, CFD and Aeroelastic Analysis Beyond IS 875
A single-axis solar tracker can clear every line of IS 875, pass its static frame analysis, and still fail in a windstorm that never reached the code design speed. The reason is uncomfortable but simple: the code hands you a static pressure, and the structure that tore apart was responding to a dynamic, fluid-structure problem the code was never written to see. This is sharpest with single-axis trackers, which behave less like a stiff steel frame and more like a bridge deck on a torsional spring. Here is where IS 875 stops, where FEA and CFD pick up, and why "passes the code" and "survives the wind" are two different questions.
ReadFour Quiet Ways the IS 875 Wind Load Goes Wrong on a Solar Array
The wind-load calculation almost never fails an audit. It fails the structure. IS 875 (Part 3) is a sound loading code, and the arithmetic in most reports is right. What moves the answer is a handful of small choices in how the code gets applied, and on a light tilted array those small moves decide which members are under-built. Here is the chain done properly, and the four places it usually slips.
ReadWhy a Cleanroom Can Pass Certification and Still Contaminate Product
A particle count taken at a handful of certified sample points tells you the room is clean where you measured. It says nothing about the stagnant corner behind a filling line, the slow recirculating loop above a microscope, or the pocket of air near a return grille that holds onto contamination far longer than the air-change rate suggests. This is where CFD earns its place. By resolving the actual velocity field and tracking how particles move through it, simulation shows you the air a cleanroom forgets: the regions that pass paperwork but quietly drive your defect rate. With EU GMP Annex 1 now expecting monitoring locations to be justified by risk assessment and airflow visualisation, that picture has gone from useful to expected.
ReadHow to Check a Cold-Formed Solar Mounting Structure to IS 801: A Step-by-Step Guide
Most ground-mounted solar structures in India are made from cold-formed steel: thin steel sheet bent into channels and hat sections. Engineers find the wind load from IS 875 Part 3, then check the steel using IS 801. Two mistakes are very common. First, engineers use the full cross-section, but thin steel does not work that way: part of it buckles early, so the code makes you use only the "effective" part. Second, engineers check only the steady (static) load and skip the moving (dynamic) effects. This guide explains both problems in simple steps. It then checks the four main members of a solar structure: post, rafter, bracing, and a 1 mm hat purlin: with full numbers, so you can see exactly where the common shortcuts go wrong.
