Quickfem, the 2D Finite Element Analysis App for Engineers and Students. FEA for Students Learn how finite elements and structural analysis works by starting out with simple models you can build directly on your phone or tablet. Play around with geometry, constraints, loads, materials and results to augment the theory. FEA for Engineers FEA is hard. Most problems are 3d and complex and require the major packages such as Ansys, Abacus, Patran, Nastran etc. But engineers have to know what to expect from these models and this insight stems from the understanding of simple mechanisms and effects. With Quickfem, you have the most convenient FEA modeller imaginable in your back pocket! Simple touch geometry creation, automatic meshing, quick mesh refinement, simple constant strain elements, and near solution instant feedback creates the tight iteration loops necessary for rapid discovery. Running on your mobile device, Quickfem gives you the freedom to create and understand structural models wherever and whenever inspiration strikes. Know what to expect. Featuring - Automatic meshing - 2D constant strain triangle FEM - Up to 100,000 elements - 3D view and edit mode - Axisymmetric FEA modelling - Plane stress and plane strain - Thermal mechanical (thermomechanical) analysis - Complex geometry, arcs, fillets, holes - Fastener representations, grounded or connected to 1 or more plates - Convergence checking through user defined mesh size - Displacements fringe and deformation plots - Strain and stress fringe plots - Equivalent and principal stress fringe plots - Maxima and minima - Unit systems, SI, US, none or custom - Default and customer material definitions - Customisable modelling environment, materials, loads, units, precision, feature thickness, mesh sizes - Example models Go to www.quickfem.com for more

Measure real-time G-forces on all 3 axes with a precision crosshair display. Perfect for roller coasters, car performance testing, aviation, and physics experiments — track peak G, acceleration history, and impact forces. CROSSHAIR 2D VISUALIZATION Experience a stunning dark-themed interface featuring a precision crosshair display. Watch your G-force position plotted on X and Y axes in real time, with a dynamic motion trail that traces your movement path. The sleek, high-contrast design ensures perfect readability in any environment. 3-AXIS G-FORCE TRACKING Monitor acceleration across all three axes simultaneously. X, Y, and Z values are displayed with precision, giving you a complete picture of the forces acting on your device. Whether you're measuring lateral, longitudinal, or vertical forces, every axis is covered. PEAK G DETECTION WITH GLOW INDICATOR Never miss a maximum reading. The intelligent peak detection system captures and holds the highest G-force values, highlighted with a vivid glow indicator that makes peak events impossible to overlook. Perfect for recording maximum forces during driving, rides, or experiments. REAL-TIME CHART RECORDING Track G-force data over time with the built-in multi-axis chart overlay. See how forces change across X, Y, and Z axes on a scrolling timeline, making it easy to analyze patterns, compare events, and understand force dynamics at a glance. G-FORCE LEVEL GUIDE Built-in reference guide explains what different G-force levels feel like — from 0G (weightlessness) to 5G+ (extreme forces). Understand the context of your measurements instantly with clear, informative descriptions for each force level. SENSITIVITY ADJUSTMENT Fine-tune the display sensitivity to match your use case. Whether you need to capture subtle vibrations or extreme high-G events, adjust the scale to get the perfect view of your data.
