freeCAD 8.4 Description

"free 3D CAD with Motion Simulation capabilities."

freeCAD is capable of full 3D pan, zoom, tilt and rotate on an Assembly of parts in wireframe or rendered graphics. Parts can be solids or DXF file imports. Available solids are extrusions of rectangles, circles, ellipses and polygons. The parts can be positioned and oriented exactly in space, as are markers on the parts. Exact specification of linear and angular velocities of parts in space are also possible. Mass and inertia properties can be user specified or automatically computed based on uniform density. Available joints are spherical (ball), revolute (pin), translational (slider), cylindrical, planar, fixed, universal, point in line, point in plane, parallel, perpendicular, no rotation, constant velocity, rack pinion, screw. Both open and closed 3D loops are permitted. The curve-curve contact allows liftoffs and collisions based on coefficient of restitution. Available actuators are rotational, translational and full six DOF. Their motions are user prescribed functions of time. Forces and torques are user prescribed functions of time, displacements and velocities in all three components or along connecting markers. Example formulas for spring, damper, bushing, beam, aerodynamic, inverse square law and other forces and torques are given. Available functions are sqrt, exp, ln, lg, sin, cos, tan, arctan, arctan2, spline, spectral density. Users can specify constant gravity of arbitrary magnitude and direction.

freeCAD can compute kinematic, quasi-static or dynamic solutions for any interval of time going forward or backward based on the assembly and user requests. It does redundant constraint removal automatically and nondimensionalizes the equations for improved accuracy and stability of models that are microscopic or gigantic. Simulation progress is animated and the simulation can be stopped any time. After simulation, the computed solution can be used for animation or Frame by frame analysis. you can free download freeCAD 8.4 now.
